I used to work for malware detection for a security company, and we looked at residential IP proxy services.

They are very, very, very expensive for the amount of data you get. You are paying for per bit of data. Even with Amazon's money, the number quickly become untenable.

It was literally cheaper for us to subscribe to business ADSL/cable/fiber optic services to our corp office buildings and thrunk them together.
