For what it's worth, my experience with the MS streaming products was a total zero. I am sure they can probably work correctly, but setting them up is nearly impossible. We need to Webcast audio only for our church. No ammount of effort could make the MS products (MS Encoder and MS streaming server) work. We finally gave up and moved to RealAudio, which worked with few problems. I would rather had the MS stuff, but their docs are all PR and no meat. Just my 2 cents... Ed Dixo
