Setting up the Sopcast was not too hard; it was actually quite easier than Peercast, and easier to change my IP address without having to change the link constantly. It's running at home, but now I need some people to help me test it, since we apparently have new firewalls at my day job (for the next couple of weeks, anyway, before I start my new job) that don't like peer-to-peer anything, let alone broadcasting, it may be better for me to get some beta testers from my friends.
Here's what you do...
Download the Sopcast client at http://www.sopcast.org/download/
Then follow this link: sop://broker1.sopcast.com:3912/29085
Let me know if this works. I may have to tweak the firewall.
