New(ish) draft: Secure Messaging in XMPP

XMPP folks:

Martin and I put together a proposal for an approach that allows for 
end-to-end encrypted XMPP conversations, including in the presence of 
MUC. Although not a completely implementable spec, this should give a 
good idea about the direction we have in mind:

Anyone interested in this work should give it a read and provide 
feedback. In particular, I'm curious if anyone interested in 
implementing this kind of thing has requirements can't be addressed with 
the high-level approach we're describing.

Thanks!
