To my knowledge and experience, my ISP has nothing against (nor does it do anything about) running servers. I have hosted a webserver for the past year or so, and a gameserver (for different games) for even longer. I have never encountered a problem where a port was blocked or speed was throttled down.
In what was this post commenting on? If you are saying that only Cable has more, you are wrong. Speeds vary by ISPs, not so much by service type. Most cable services have crappy upload, so that is definitely not the answer to my questions.
I will call my ISP and see what kind of stuff I could get. Right now I'm paying $35/month.
