I like the idea of using email. Occasionally, though, an alternate
transport layer will be necessary, and I'd hope that the endpoints
wouldn't have to know too much about it.

Based on the email I've gotten, it looks like lots of people have tried
to solve this. Would anybody be interested in an informal working
group? Let me know, if so. If nothing else, I'd appreciate some review
of my draft specification.
