Well, there's also people like me: I prefer and am able to use
Plan 9 the bulk of the time, but have a few particular tasks I
need Linux for. It'd be nice to be able to stick the Linux box
in a little jail.

I'm very glad 9vx exists: I now have Plan 9 on my OS X laptop.
I'd like Lvx to stick on my Plan 9 cpu servers. As it stands, I'll
be converting one of my older cpu servers into a linux box in a
few weeks. That makes me feel unclean.
