We're perfectly willing to scale all the way back to Alternet or U.S. if that is the consensus. So far, you're the first to weigh in on either side and I'd welcome additional comments.
What we're trying to achieve can be accomplished with a ttl as low as 16: recording everything they do on a hard drive. We have about 10 Gbytes allocated, which holds ~1000 hours of audio. What we're trying to do is couple the audio from House and Senate with the Congressional Record (the "transcript" of the proceedings as edited), plus use a variety of other tools (e.g., possibly speaker recognition) to make an audio-on-demand server.
The idea is that you probably don't want to listen to everything, but there might be one or two speeches that make sense. Once we're able to extend our network from the hub room of the U.S. Capitol Building into the office buildings, we can also add relevant hearings.
Again, a low ttl is fine with us. You notice we're only sending at 16 kbps GSM and notice also that the Senate and House are typically in session when it is night in Asia and Australia. Our theory was to try it at a 127 ttl for a while and then scale back the ttl during periods of heavy mbone usage (e.g., the various cheap stunts, plus conferences, IETF week, NASA launches, etc....).
I'm a bit puzzled about the horror when "real" stuff is put on the net. Seems to me that a 16 kbps stream is the same whether its another demo or if its the U.S. House. I happen to think these tools are real and that using them for real applications is a useful "social development."
You've heard Marshall McLuhan's famous quote on the "medium is the message"? I think its important we move to the point where the medium *isn't* the message. The Internet has far more potential than simply using it for talking about how to engineer the Internet.
