i hosted a 14 man CS server, webpage, email server, and voice server on TW a few years back. Would have bouts of lag every few hours for about 30 seconds, otherwise was pretty good considering.

And yes, they block port 80, but i just forwarded web traffic to port 8000 and all was good.

I also have a dedicated server in a colo in dallas on a ~12gbit fiber mesh, so if anyone wants to host something let me know and we'll come up with something. web, email, voice, whatever.
