Sunny has used checkpoints fairly extensively in the past to prevent double-spends and attacks. Don’t know how often he does them currently.
Is the current state of PoS sufficient to thwart an attack?
The more I know about PPC and read about the running attacks, the higher I appreciate the decisions of Sunny. The Check-Points, and the reasonably low inflation.
I know of course the disadvantages must be put into account and solved. It seems that PoS becomes more important by this time, and Check-Points can be removed (but better later than sooner).
Is there anyone out there that has a reasonably accurate technical knowledge of the state of the network and its vulnerability at this point of time?

In the second post Sunny is answering my concern about 51% PoS attack. The more coins are distributed the lesser chance of any successful attack, PoW attack cannot be executed at all without PoS and that’s why I like PPCoin! 
The PPC price has hovered near 0.00114 all day today. Apparently PPCers don’t much like Cryptsy or Bter for trading judging by their volume. We’re hanging in there at #4 on the marketcap rankings between NMC at $3,255,997 and NVC at $998,018. Feathercoin is hovering just below at #6 with a $802,016 valuation after 2044 BTC was pushed into it just today! That’s a lot of bitcoins buying a 51% attacked coin.
Bitcoin made another step towards mainstream significance today getting listed on the XE currency exchange site though you can’t trade it there yet. http://www.xe.com/currencyconverter/convert/?Amount=1&From=XBT&To=USD
On our forum here it looks like a bunch of the spambot members were pruned and I’ve been noticing a much lower level of spam posts. Great job mods!

In the last days it seems the PPC/BTC exchange rate has stabilized at values between 0.00105 and 0.00115, with only occasional outbreaks, despite some pump-and-dump intents.
Some pics:
1-month-chart shows the stabilization and perhaps a triangle pattern about to close:
PPC-USD chart from Vircurex (low volume, but interesting):
It seems we have bottomed out. The bearish channel was clearly broken:
Now we need a lot of volume to confirm this. But I think it’s a very good moment to buy.

That giveaway thread on bitcointalk I opened took care of it ;D
That’s a joke of course…
I’d agree, good time to buy. I have a lot of confidence that we are seeing a price floor right now. There’s certainly plenty of room to go up!
Time for an update. A bunch of the spambot forum users were cleared out taking us below 1500 but the number of users seems to be going up awfully fast again. On BTC-E there’s been a 350+ BTC bid at 0.00100 that appears and disappears - maybe it’s the manipulator from the good old days of bitcoin? The fundraiser for the logo appears to have stalled out at $95. It might get some more traction if someone would agree to accept cryptocurrency donations and forward dollars to fundraiser. Sunny has posted a new weekly update but no word yet on pulling over the bitcoin 0.8.2 features yet. https://bitcointalk.org/index.php?topic=114994.msg2501124#msg2501124 51% attacks against altcoins are becoming more common. These could keep all but the largest alts from being useful and were used to kill a few coins back in 2011. For PPC the threat will keep the necessity for checkpoints around for the near future. https://bitcointalk.org/index.php?topic=236498.0 The MTGOX feature request now has 50 requests to add PPC trading. https://support.mtgox.com/entries/21676064-Please-Add-Peer-2-Peer-Coin-PPC- This compares to LTC with 184, FTC with 125, NMC with 56, TRC with 4, and CNC with 1. The amount of interest in FTC continues to amaze me. Right now PPC is holding in a stability pattern just above 0.001. Bitcoin is right near $100 and hanging on. Seems like the markets are just catching their breath and waiting for a trigger before we’ll see any significant action. As always if the update is informative feel free to boost my karma.

@Topic: I am pleasantly surprised how PPC is holding its price level versus BTC fairly well, taking into account the recent price spike in BTC and the (probably related) crash of some other altcoins like FTC, CNC and TRC.
Logo project is fully funded now (or will be once the final BTC clears pending on my account).
Excellent!
It will be great to get this squared away. No more confusion on what is the “official” logo.

Agreed, not that its the most important thing to happen in PPC, but it is movement and that’s a positive and frankly once its out of the way we can move on to other projects.
More buys at about 0.0019 at Vircurex - BTC-E slowly ascending too…
RALLY? 
Don’t have time for a full update tonight but I’ve noticed that hashing power has increased to where we’re once again just under 400 coins per pow block found. Reward 399.81.
Also PPC has gone up against BTC which is up at least on MTGOX on the news that they’re entirely suspending USD withdrawals for two weeks. Meanwhile gold, silver, US treasuries, the Dow, NASDAQ, S&P and AUD and CAD are down for the day. Very impressive relative performance by PPC considering.
After a pretty bullish Saturday morning (in my timezone) a large dump at BTC-E brought PPC value from 0.0013 temporarily back to 0.0010. Now it’s at 0.00117 again, back in yesterday’s price range. I have missed the buying opportunity 
FTC and CNC have returned to their “normal” per-unit prices far below PPC’s price. I have predicted it: it was a simple pump-and-dump game.
Things are looking strong on the mining front for PPC with the block reward down to 393 coins. It may be time for an update on our inflation rate vs. the other cryptos. MTGOX mentioned adding LTC in July and the price briefly soared. No mention of any other alts, even NMC which they’ve hinted at before. Our feature request now has 60 likes on there. https://support.mtgox.com/entries/21676064-Please-Add-Peer-2-Peer-Coin-PPC- Over at BTC-E the big news is the delisting of CNC causing it to drop 43%. There is a highly unsubstantiated rumor that PPC and FTC may also be in BTC-E’s sights for delisting: https://bitcointalk.org/index.php?topic=240870.msg2554233#msg2554233
Sunny has added a basic trader ratings system to the PPC Marketplace though personally I hope he’ll soon spend some time working on the cold locked wallet. https://bitcointalk.org/index.php?topic=241054.0
Vircurex had a massive spike up which briefly brought prices up a bit on BTC-E but then there was a momentary drop which also bounced back. The overall is that in spite of comparatively lower volume than some of the other alts PPC appears fairly resilient and relatively stable. As always, thanks for your Karma votes!

I will update the stats at about June 26/27, then I will have the first complete monthly stat (May 27 - June 27) and 30-day-stat (May 27 - June 26).
Thanks for the market report! I hope the rumours of delisting PPC from BTC-E are not true. Vircurex has far too high withdrawal fees and the other PPC exchanges haven’t the volume for reasonable trading. We need, although, a real PPC-to-USD and PPC-to-EUR exchange with real (not only VouchX and PerfectMoney etc.) fiat deposits and withdrawals. As I think that addition to MtGox will take at least some more months, it could be better to try to convince smaller exchanges to add PPC. I have thought about The Rock Trading, as they have already added LTC and have pretty good deposit options (SEPA, for example).
