check out the Pho list - www.pholist.org - these guys are talking about
doing such things on a digital level - in their case to add Digital
Rights Management to shared music and make people pay up (ugh!). it'd be
nice to put this sorta technology to a more noble use.

i believe there were people on linux-audio-user -
www.linuxdj.org/audio/lad - who were trying to do something similiar?
