regular old encryption totally rapes comcast's filtering. at my parents' house, they have comcast, and i just downloaded geass/kyouran/some old tenchi shit the other night, at ~400kbps. so don't tell me encryption doesn't work, because without it i can't get anything above 2 or 3kbps, but with it enabled i get normal speeds. encryption is god. i sacrifice small animals to a protocol encryption effigy daily. maybe that's why it works for me.
