Interesting that they are working on OTR. I generally applaud any OTR implementations (or any form of encryption), but why would a company need plausible deniability?
OTR is something a lot of people use and trust. It also makes it easier for users to use our service with third-party clients later that already support OTR. Plausible deniability might not be very important for companies, I agree.
We are also looking into other protocols, for the same reasons TextSecure decided to modify OTR: both parties need to be online to exchange keys.
