Great summary Trevor. Two notes to add: *Apple iMessage, Wickr and BBM Protected can all be described as opportunistic encryption messaging systems that have been very successful deployment-wise. Although AFAIK none of them provide any MITM resistance if the centralized public key servers are compromised or misbehave.
*The general discussion of opportunistic encryption could mention tcpcrypt ( http://tcpcrypt.org/), one of the more ambitious efforts to get this out on a large scale.
