Bitwise IM (Score 1)

Bitwise is a rather nice IM network/client that's already available for Windows/Mac/Linux. It uses 128 bit Blowfish encrpytion for the free version, 256 for the Plus version and 448 bit encryption for it's enterprise solution (Bitwise Professional). Apparently the Professional version also provides the logging capabilities required for compliance regulations too. Closed source though :\
