It's been one month since 327 (http://xmpp.org/extensions/xep-0327.html) was published, and some further work on the spec has been done. Progress since then can be seen as a diff here: https://github.com/rayo/xmpp/compare/730f5f85e755cfa2d040c7455fa6b01e0c747c3e...rayo
We still have a collection of outstanding issues on our issue tracker: https://github.com/rayo/xmpp/issues, and I am sure there are issues with the spec that we have overlooked, or things that would be more satisfactory to the XSF. I would love to hear feedback that anyone could share either here or as issues on our tracker, along with any suggestions for improvement. This is the first XEP that I've written and it's a big one... Regards, Ben Langfeld
