I'm toying with some ways to use multicast to download shows to an
unlimited number of users concurently, and I'd like your input. First, you
must have a multicast enabled Internet connection to get it. Next, I'd
like to get some feedback at what bitrate downloads are possible/prefered.

The application I'm using spreads the data across multiple streams at
different rates allowing each client to join as many or as few streams as
necessary to minimize packetloss. The data is encoded in such a way to be
completely reliable even with packetloss, and the client then saves the
.tar file of the show.

I have a test stream up now for folks to bang on:

On there is a link to test if you are multicast enabled, a link to
download the client (Windows only right now, but Linux on the way soon),
then a link to the download streams themselves.

I .tar'd the .shns and .md5 into a single file so that I can server them
on one stream. I could also .tar all the disks of one show which would
allow me to offer more shows at one time. Your call.

Right now, the streams adapt between 100kbps to 500kbps. Is this
enough? Too much? The box sits behind a T1 right now so I could turn up
the max rate, or turn it down to offer more shows.

If we have enough etree'ers multicast enabled, this could be a good way to
distribute new shows in a hurry.

Ideas?

Feedback welcome! Thanks,
Greg
