Off The Record Encryption Those guys at Slashdot are still good for something. Off-The-Record Messaging is an encryption protocol with some very nice properties for instant messaging. As per their website: 1) Encryption (thank goodness) 2) Authentication 3) Deniability, and 4) Perfect Forward Secrecy.

I'll have to read this in depth to understand what's going on here, but this is exactly what I want to add to Gush. I knew holding off implementing PGP for Gush would pay off. I hope this isn't too good to be true.
