I think something like blackhalo might suit the Peercoin community. Decentralised trading platform/exchange. I think the ported btcd might make this easier. The platform also allows for anonymization. Couldn’t find the code though after a quick check.
I agree that minting functionality might be good for the exact reason @mhps provides earlier in this thread. Having different codebases would strengthen the blockchain further although have limited value given the current stability.
Regarding OT, I guess we have to wait for the Bitcoin launch before we get attention from their developers unless someone is prepared to grab their codebase, but that might prove to be challenging.
Anyway, we always knew this would be just a step towards other developments. So if it is considered ready and stable now, I would say congrats with this achievement
