I like that but just to check - what you're calling IM here
does work with OTR, right? OTR requires an e2e roundtrip and
IM otherwise seemed to be more fire-and-forget, at least e2e.
So is there a possible terminology glitch?

Put another way - I know that OTR will work, but there'll now
be a few messages at least to do the handshake and not just
the one, so are we actually doing a chat session and not an
IM at that point?

Cheers,
S.
