My solution to this was to pay a friend in the states to share his residential connection. I'd like to see them try and block Comcast's residential blocks.

There's potential here for a middleman to write software/develop hardware that can share residential connections whilst filtering destination IPs (e.g. allowing AWS addresses) to try and minimize the potential for abuse with the goal of discouraging traffic other than that required for Netflix. The user using the service would pay a fee which the middleman would take a cut from, with the rest going towards the home owner's broadband costs.

Payment is still problematic, ideally I'd be using a US bank account and credit card. But if they start clamping down on use of 'foreign' credit cards they will alienate those taking vacations etc.
