When I first heard about this extension to CALEA (the idea of tapping VoIP has been around a long time), I was enraged. But, now, I really don't care all that much. Let them monitor away. I've got my secure key-exchange protocols, I've got my AES and alternatives, I've got my RSA. Let them monitor my secure traffic all the want. Until they get capable quantum computers, I really don't care about being monitored all that much. My biggest problem with this though is that the people they're trying to spy on...well, they know the same things I do and are going to secure their communications equally well. I don't see this doing a whole lot of good.
