[13:48:16] <Ted> ox-plow for the win!
[13:48:50] <Adam Roach> Slide 7: XMPP Open Issues (1)
[13:51:32] <Kev> I think the concern here is that you end up with problems knowing if two entities are the same, or are different, when you don't know what version you're receiving.
[13:51:47] <Adam Roach> Kev: you want me to take that to the mic?
[13:52:01] <Kev> If you would, please - although there's a discussion on the list as well.
[13:53:54] <Kev> Sorry, audio caught up. If we don't have a (realworld) chance of a conflict/split between entities.
[13:54:04] <Kev> ...then this is largely moot.
[13:55:08] <linuxwolf> psa: If you'd like your question said, then please prefix with "mic:"
[13:55:20] swainner joins the room
[13:55:25] <Kev> <stream... version='2.0'> for the latter? (stringprep upgrading)
[13:55:31] <Kev> s/upgrading/migration/
[13:55:37] <linuxwolf> /-:
[13:55:53] <Adam Roach> I'm not sure how to vocalize that. :)
[13:55:56] <Ted> Are we going to see any environment in which one set of parties is evaluated using 6122 and another using 6122bis? I can't see how an evaluating party would do that.
[13:56:19] <Kev> Adam Roach: "Maybe we need to upgrade the stream version, if the stringprep/precis migration is a big problem".
[13:56:28] <Adam Roach> ok
[13:57:53] Randall Gellens joins the room

[14:07:19] <Adam Roach> Slide 18: Mix-n-Match
[14:07:23] <Kev> The stream seems to have cut out for the last 4 slides for me :/
[14:07:29] <Tobias> for me too
[14:07:31] <louiz’> idem
[14:07:37] <Kev> Back.
[14:07:41] <stpeter> louiz’: :)
[14:07:56] <louiz’> well, not that long, I had short cut, and then a longer one
[14:07:58] <louiz’> stpeter, hi :)
[14:08:24] <Adam Roach> Slide 19: Caveat Emptor
[14:08:36] <louiz’> (and that’s during the topic that interests me the most :()
[14:09:12] <Adam Roach> Slide 20: Open Issues
[14:09:13] <stpeter> BTW slides are at https://datatracker.ietf.org/meeting/81/materials.html#wg-xmpp
[14:09:58] mph joins the room
[14:10:12] <Adam Roach> Slide 21: References
[14:10:13] <louiz’> thanks
[14:11:45] <Kurt> I missed the audio... my only comment, which Matt is well aware of, is to make sure that the key exchange supports, to the extent reasonably possibly, other XMPP signing/encryption extensions... including different key formats (including certificates).
[14:11:56] <Adam Roach> Mic?
[14:12:06] martin.thomson joins the room
[14:13:00] <Kurt> adam, if you could echo that on the mic, that's fine. That comment is more for the WG as a whole than Matt. Matt understands the issue, I believe.
[14:13:22] mph leaves the room
[14:14:33] hildjj leaves the room: Disconnected.
[14:14:44] Cary Bran leaves the room: Disconnected.
[14:15:00] <Adam Roach> FWIW, taking a comment to the mic has the useful side effect of usually getting it into the minutes. People will refer to minutes after the fact. The XMPP logs are archived, but referenced only infrequently (if ever)
[14:15:30] bpenfield leaves the room
[14:15:40] <Kurt> key point is that the key/cert mech needs to 'generic', not just support e2e.
[14:15:54] <linuxwolf> noted…again (-:
[14:16:36] swainner leaves the room
[14:16:37] <Adam Roach> Switching to geopriv chat room.
