1. I don't think Jitspoe has that part GPL yet, and there's the whole cheating thing which may prevent it's source from being released.
2. PPC, probably. AMD64, I run it fine with some lib32's. You can request proper PPC and AMD64 support in the 2007 requests thread, I know that 64-bit is already in there once for something. Jitspoe probably doesn't have AMD64 or PPC to work with, but I'm sure we can drag a dev into it who he can trust, I don't think he'd be willing to lend me the source though since I hax.
