I think we should push for Axolotl (the cryptosystem used by Signal, which is an improvement on OTR) support in Ricochet and get a Ricochet phone app.

Ricochet uses Tor hidden services to anonymise your social graph, which is something you don't do with Signal (not to mention that Signal does identity key lookups with phone numbers). I'm not sure there's a low-latency way to do VOIP anonymously. The best method I know of is to literally record and send audio files, which have a few seconds of latency.
