As this is the first release, I'm sure that the community will have lots of questions about how it all works. As questions come up, we'll do our best to get the questions and answers added to the Peerunity wiki, but as it will take us a little time to build that out, I'll first add the response here, to keep them in one place.
Do I need a new wallet? What will happen to my coins?
Because they use the same wallet.dat file on your computer, both the Peercoin reference client and Peerunity are accounting for the same coins in the block chain. It is recommended, however, as a general practice, that you keep a backup of your wallet.dat in a safe place. You can create a backup using the Peercoin reference client before you install Peerunity from the menu options.
Can we run peerunity and reference client at the same time? e.g. are they using the same ports?
Peerunity uses the same port that the reference client is configured for, so that they can connect to the same network. You should not run the two applications at the same time, because the default settings will use the same data directory. Unless you're trying to run them both for a very specific reason, using different copies of the block chain and wallets.dat with different "-datadir" settings for each when you launch the applications, there should be no reason to attempt concurrent use.
Can you download Peerunity to directly replace your Peercoin client (in the same way that downloading v0.4 replaces v0.3)? Should I have to uninstall the Peercoin client first?
You don't have to uninstall the reference client, unless you really want to. Having them both installed won't be a problem, you just shouldn't attempt to switch back and forth between which one you'll use. If you do, you'll likely run into a known issue.
Wait, did you say that there's a known issue? What is it, and is it going to affect my coins?
The issue is documented here, "Changing wallet software from Peercoin to Peerunity to Peercoin causing DB exception", and will not affect the coins you have in your wallet. The linked issue report includes instructions for fixing the database version mismatch that occurs. We're actively looking to find a solution to this issue, but in the mean while, we hope that the vast majority of peercoin holders who install Peerunity will find that the added functionality and cleaned up user interface will provide all you need for now, and you won't need to switch back to the reference client.
What's next for Peerunity?

Who's the "we" you keep talking about when you refer to the Peerunity development team?
Peerunity 0.1.0 has been a truly community-based effort. Developers, testers, and designers who have contributed code, validation, and visual assets include:
(If I've missed anyone, I'm very, very sorry, and will get you added to the list. Trying to combine contributions across the repo and PeercoinTalk wasn't as straight-forward as I had hoped!)
