We actually talked about this earlier this year -- including the idea
that the qemu image could be already booted and ready to go (which
would make it much less painfully slow) but that would require more
than a CD (as the RAM image alone would have to be 256MB).

Paul Sladen successfully booted qemu with the casper image from the
LiveCD back in February but it required a small change to the boot
scripts and a change to one of qemu's constants:

I still think it's a very attractive idea but mostly as a "gee whiz
wouldn't that be neat" thing.  If someone else wanted to pick up where
Paul left off and make it a reality (maybe get some performance stats)
that would be pretty cool.  Based on Paul's work I'd bet it would only
require some very simple changes to the LiveCD.
