Quite possibly, yes :-)

Over lunch yesterday, Stu and I were tossing ideas around that could 
greatly improve the performance of his emulator.  We came up with at 
least a couple of reasons why having a virtual machine run in the kernel 
was a good idea (for some definition of good idea), one of which is 
access to kernel facilities which just aren't available to user-space 
(pick any number of such facilities...we were focusing on those 
pertaining to I/O).

Anyhow, it might be fun to LKM such a virtual machine for two pretty good 

	- proof of concept
	- sick, twisted, cool hack

Pick the one that's more important to you.  :-)

If course, this all depends on how much time you have to work on such 
silliness, but whatever :-)
