Good read, but unless I missed it they don't say if the software is open source or not! Just looking for a way to verify the communication content cannot actually be opened as it passes through their server on the way to its destination. I always like the notion of open source where I or others I trust can compile private binaries from the public code. Its the ONLY way to know for sure! I can always pass my private binaries to selected friends if they lack the expertise to do the build.
