Yeah, my apologies if this question has been answered before, but as
you point out, this is something that is desired by a great many
people.  Far be it for me to pertend I understand all of the issues
involved, but as a project I'd find it an interesting one to at least
work on.  Maybe just a "simpler" off-line version would be easier to
write, and wouldn't require kernel changes?
