Sounds crazy.  It's got some hack value, I guess.  :-)

How about x86 to Java?  Here's a starting point:

I bookmarked it a long time ago, and I'm mildly intrigued, but not 
enough to actually try it out, I guess.

Of course, since you'd have to emulate the x86 platform anyways, I'm not 
sure what running Xen on top of it provides...

I can't imagine anyway that it's going to be fast.  I'm imagining that 
it would be like running Xen on Bochs, but much slower.  You'd have to 
emulate physical memory and the MMU using garbage collection.

BTW -- I'm still working on moving the Kaffe server over to a Xen 
session on my new server.  I'm a bit slow - I'll get it done someday. :-)
