Yeah, and we'd have to be super careful about that.

Right, I think that people forget Maildir was not designed as a mail
_folder_ but instead as a mail _drop_ (a place where you store mail to
retrieve it).  Yes, Dovecot uses it as a mail store, but I believe it does
a lot of caching.  One of my plans for redoing the internal API is to
support different backends; the three obvious candidates right now are
MH, Maildir, and IMAP.
