For a while, Kip Macy was working on it, but I am not sure why he stopped.
Last time I checked, a college student was working on it for Google's
Summer of Code

I believe the goal is to allow FreeBSD to run under DomU without
SMP or PAE support in 7.0-RELEASE

On a somewhat unrelated note, there was a posting today on freebsd-announce
about a Jail rc.d script privilege escalation that makes it possible for
root inside the jail to overwrite files on the host system outside
the jail with arbitrary content.

Sorry to derail slighty, but I figured it was worth mentioning
