FYI, Sen. Ron Wyden is pretty much the only US congressperson actually -doing- anything about this. He is relentless in his attacks on the industry and understands the technology. I saw him at DefCon and yes, he sounds like a politician, but he's fighting the good fight.

FTA:

In a statement, Senator Ron Wyden said “Venntel has stonewalled Congress for months and refused to identify the sources of the data it is selling to Customs and Border Protection and other government agencies. The U.S. needs far stronger laws to protect Americans’ privacy, and ensure transparency about where our data is going."
