I was surprised that everything behaved/performed as well as it did, and
in truth as it currently is it should be acceptable for the demonstration.
Yes, JackLab and Musix are Live CD distros, and you may be right in
thinking that would be the best way to do the demonstration. I did want
to fold Linux audio into a virtualization demo to kill those two birds,
but that's not critical.
