Encrypt Audio/Video Hangouts

It would be really cool if this could encrypt hangout audio and video before passing it to google.

I'm not sure how viable this would be, and any number of things could break it.

Possible problems:

1. Can't intercept media
2. Google re-encodes video after getting to their servers
3. Thumbnails are probably resized before video gets to the client, breaking encryption

I found this paper: Compression Independent Reversible Encryption for Privacy in Video Surveillance, which looks promising for problems 2 and 3.

Oh and there's also a bandwidth problem, namely, can JS handle the huge encryption bandwidth?
