There’s also the fact that Jabber and the multiple device presence issues make it easy for a message to be lost, or unknown if it’s actually received. It will silently fail, and we should not expect participants in the IETF to be able to run, troubleshoot and repair a XMPP server and client set. > I use pidgin/libpurple, and I know that there were times > when there were significant security issues with it.

This has it’s own issues, because their XMPP support didn’t notify you of channels you were added to, leading to the blind messaging problem above. > It would ideal if Slack could XMPP s2s out to IETF jabber servers, but > I would not be surprised if this is not supported. Slack model is on a pay per user model (primarily), so s2s on XMPP is not going to work right. You can integrate slack workspaces together, lets say you have one called example1 and example2, you can link them and have shared channels. This doesn’t really match the IETF communication model. I have to say this: If my kids can figure out how to do this and the IETF can’t, we’re clearly missing something, or attempting to over-engineer or over-religion it. - Jared
