You just need to meet up once in a while -not a problem for most communication-and exchange random data which you use either to encrypt the whole message one time pad style, or piece by piece as passwords. One pair of random data per contact. Lavabit or spookmail or whoever don't get anything exciting to look at other than who is communicating.
