Sure.  It's related, and you've got a pointer to my stuff on your site :-)

That would hurt.  You definitely want to be able to map pages and have them go 
where you want.

Posix compatibility is definitely not enough.  I think the biggest problem 
would be the ability to intercept and modify Linux system calls.  Nothing 
works without that.  There is also code that is written with knowledge about 
how the system call path works.  I'm going to get rid of that, but for now, 
it's a definite portability problem.
