I like that - it's a different aspect of email to the one I was
considering, but it would be useful, and not too hard to implement either.

I was thinking that the choice would be for the recipient and manual,
rather than automatic. But automatic replies via XMPP could be
determined by looking up the user's Jabber profile, where a field could
hold a list of preferred communication methods, or a Disco node that
declares the sender would prefer Jabber messages. If it's possible to
reliably link an email message with a Jabber account, then all the other
information can be got via Jabber.
