Steve,
I'd be happy to work with you on adding this functionality to our
Voyager Multimedia Server (http://www.mcs.anl.gov/fl/research/voyager).
It's a recording and playback server that currently serves not only the
AG but other purposes as well.
If you are interested drop me a line and let's see if we can figure out
how this would fit. I have some ideas that might help you.
