Seems to me that XMPP already covers all these use cases of COI? Both XMPP and email use essentially the same addressing format but XMPP uses XML formatted messages whereas email uses HTML formatted messages (it's worth noting that XMPP used to support HTML messages).

So you could "send an email" in XMPP just by composing a message and sending it to what amounts to an email address (technically the bare JID). The XMPP client would just need to close the chat window after sending the message to make it seem like typical email experience.

XMPP also has the advantage that it was designed with the IM and multi-user chat use cases in mind (e.g. chat state notifications, message corrections, moderated/members-only chatrooms, etc.) but also can support email use cases.

I think it's easier just to set up your XMPP server to handle IMAP authentication.

Really surprised that they use XMPP. Since you don't really hear anything about XMPP anymore, I think most people assumed that it's dropped off in usage/popularity (or people have moved to some other proprietary solution).

I've always thought that XMPP would be useful for games, just surprised to hear that people are actually doing it.

> We're all technical folks here. What possible reason could there be to close the site every Sunday morning for 12 hours?

Sometimes the reason isn't always purely technical. Especially in the government, there could be bureaucratic reasons that cause really un-intuitive behavior that's pretty much unheard of in the commercial world.

They could be exercising migrating to their COOP site and when asked "how long does it take for the site to FULLY come up?" the contractor said 12 hours to be on the safe side. If you account for things like acceptance testing done by government employees, 12 hours is unfortunate but not unreasonable for the government.
