You know, as the guy that wrote OfflineIMAP....
What would be REALLY cool would be a way to do an
OfflineIMAP-style synchronization over NNCP. That is, notice that
certain changes have occurred on the local end, transmit commands
via NNCP to cause those changes to occur on the IMAP server, and
vice-versa. As far as I know, there is nothing out there that can
do that right now. The closest you might come would be to use
OfflineIMAP on a system with Internet connectivity, and then
something like Syncthing to share a Maildir tree in an async
fashion. However, I'm not really sure how reliable that would be.
It is entirely possible it would have significant drawbacks.
Syncthing and NNCP are interesting partners. I wrote about a few
of the possibilities at
