It looks like OTR will never be implemented for Empathy. But two years after Snowden end-to-end encryption is really a basic requirement for every secure chat program. A few weeks ago I read about a promising protocol called OMEMO which seems to overcome all shortcomings of OTR and GnuPG with respect to instant messaging.

This would be a option for Empathy to finally support end-to-end encryption.

Note: During the Hackweek 15, I may only learning about OMEMO and learn code of Empathy, would not implement this time.
