When I lived in college with 3 roommates we butted up against our 250g data cap with comcast all the time. Steam Accounts, Netflix, Xbox live, Hulu, etc made it tough. The worst part was that we didnt even have an option to pay for more data, They just throttled after that. It was super frustrating. Unfortunately they have a monopoly in my area so I just have to deal with it. Keep fighting the good fight man.
