I don't know of anyone else who's looking for this capability though so as a result I don't think there's anyone working on it. I'd guess that some of the x86 native execution support would be generic enough that it would be useful in porting the capability to other ISAs though. > And would you venture a guess as to the time > frame of the x86's model/system release to the public? I believe the current code will be available soon... we've got all the major legal issues out of the way and what's left is mostly the grunt work of updating licenses etc. What we have now is somewhat limited (syscall emulation only, no x87 or SSE support); I'd estimate a few more months until we have more complete full system support (Gabe can speak up if he thinks otherwise).
