Technical question about streaming audio

Does anybody know the technical details of how streaming audio in SL works?

Specifically, I need to know this:

If I set up an audio stream on a plot of land, say my favorite Winamp Playlist, and stream it to SL, does the SL server capture the stream and re-broadcast it to the user, or does the end-user's computer directly attach to the audio stream from the original source?

Example: I create a Shoutcast stream on my computer and set it up my land so that others can hear what I'm currently playing on Winamp.
Either the SL server connects to my computer, using 64k (or whatever) of bandwidth, or all the users' computers connect and use 64k EACH. Since I only have 256k outbound, I could only host 3 users aside from my own SL session.

Has anybody tested this process?

Each client connects to the streaming audio server individually, so you can indeed only have very few listeners at 256kbit/s uplink.

ok. thanks.

So much for Weird Al night at the night club. hehe

There are companies that provide Icecast/shoutcast hosting - you send one uplink stream to them and the listeners connect to their server to receive it (which has alot more bandwith than you). Of course they tend to want money for that
