RE CIA v. FBI - I wouldn't be surprised if it ended up being a loose handshake that they (CIA/NSA/FBI) will allow Tor (benefits CIA), in exchange for technical assistance in investigations (benefits FBI) -- namely the ability to own an endpoint. Don't need to own the service/protocol if I can own the host it is running on.
