That sounds really useful. I suspect that:

a) Even quite experienced XMPP developers probably don't know what's on
offer, and what they provide.

b) It'd help focus discussion enormously, by enumerating the requirements
properly.

A comparison document such as you're suggesting could probably be done as
either; the process overhead isn't important either way. I suspect that
longer term, it'd be nice to maintain it (unless we think we'll find the
Final and Ultimate Solution to Encryption (FUSE), in which case it'll be
only useful as a snapshot.

If we want a "living document", then the XSF affords us that relatively
easily, whereas if we did it as an I-D, I wouldn't press for publication as
an RFC at all. In that sense, it'll be lower process within the IETF.
