I love the Internet.
this project on Pharyngula, I got replies from several people, from places as far away as Texas and California, and several demos.
I’ve also installed Audacity 1.3. This is, unfortunately, a beta version, but it has an important new feature: the ability to have multiple “clips” per audio track, and slide them around. This makes it much easier to take two voice tracks and splice them together into a coherent dialog.
I still need more voices, though. Lawyers in particular (odd, during the trial I thought Eric Rothschild was a hero), and no one seems to want to be judge Jones (maybe nobody wants to play a liberal activist). There are plenty of short parts, too, if anyone wants them.
