OK, some of us discussed this topic again yesterday:


Please read the meeting log to see what was discussed.

In general, we decided (again?) that only ESessions and XTLS really make
sense to pursue further (i.e., not OpenPGP, S/MIME, OTR, or xmlenc).

Follow up so far:

1. I chatted with Brendan Taylor and he said he looked into OTR some
more but realized that it would not be any easier than ESessions if we
want to encrypt entire stanzas. He may report further on that.

2. Ian will work on a revised version of XEP-0210 (requirements doc) so
that we can differentiate between what is necessary and what is nice to
have (well, *really* nice to have). The main requirement that people
think falls under nice to have is deniability.

3. We will work to compare TLS against the XEP-0210 requirements. This
may involve talking with some TLS experts at the IETF or elsewhere.

4. We will work to compare ESessions against the XEP-0210 requirements.

Feel free to join the conversation if you care about these issues. :)
