Eg. the suggestion someone made earlier about adding signing of OTR
keys. Any sort of signing should be a no (it's not part of the original
OTR protocol, and is contrary to its goals). I've seen this sort of
thing suggested a few times elsewhere.

Rereading that paragraph, I'm confused as to what I was talking about
too; possibly ignore it and just read that as "we should keep OTR's
goals in mind as we develop to make sure we don't inadvertantly leak
information and break one of those goals".

Different kind of deniability (sorry, my message was confusing as I
mentioned both, and it may have sounded like I was talking about the
same thing). You're probably right; don't know why I even mentioned that
(the initial OTR stream setup will always show that OTR was being used,
even if OTR messages are designed in such a way that there could be
plausable deniability that OTR was being used). I don't think it's
something we should concern ourselves with anyways.
