Having investigated it reasonably thoroughly, I do not believe there
is a FUNDAMENTAL technical challenge, as long as the IMAP server supports
UIDs (and it seems to me that all of them do).  Remember that currently
messages can be added to MH folders at any time and all of the nmh programs
handle that just fine.

I talked more about a possible client-side mapping between IMAP UIDs and
MH message numbers here:

Like I said, I think this should work fine; there is only the minor matter
of writing the code.
