I've capped the server at 4 users. That leaves each user at about 15 kb/s. Not great, but acceptable. Its definetly the best balance of availability and speed.
If anyone else wants to run a server, I'll send you the software. The software takes up basically no room, so really all you need is the free space to keep the shows on your hard drive. And you need a good internet connection. It's not very difficult at all.
If anyone is interested, email me:

EDIT: Also, when people upload, I close the server to give them full bandwidth, so that could be a problem you're having as well.
