[Telepathy] Fwd: GSoC Project: Add OTR support to Telepathy/Empathy for XMPP

[wolfrage8765 at gmail.com]

João,

This looks good, thank you for the information and update. Now I am
not very strong as far as GIT goes, so what would be the best way for
me to incorporate your changes in my gitourious repository. Just apply
the raw patch? Then i think we still need some one to review the spec
work to get it approved, can Will do that for us?
As for OTRKey, I agree it should get stored with the contact. I think
that is part of Folks and I am not sure if telepathy handles that or
if that would need to be achieved through Empathy. Tomorrow I will be
doing some more work and we can discuss everything more.
