that's an interesting idea. Do you have a build environment for the initrd
that you'd be willing to share (or suggest). Obviously it should be a cut
down environment, not a gnu-libc one where you can't get a static binary
down to less than a 1/2 meg. Busybox can get you a long way, but doesn't
cover ssh. And xen needs a lot of python... hhmm, that would be a really
cool project, but not a trivial one.
(yikes, my centos python install is 20 meg, in that scale, maybe skipping
glibc isn't significant.)
