Alternatively, store your mail in ~/imap/ and use IMAP=20
at home and at work to read your mail without necessarily
copying all of it over; if the meta-information is kept in
the IMAP back-end, you don't need to synch anything on
these mailboxes, you just us a "longer connection" to the
IMAP daemon.

Storing metainformation with other backends (e.g. nnml)=20
obviously helps in the rsync case, but it should also make
it possible to move a group wholesale from one backend to
another, without losing marks/scores/kills/etc.   For
example, if I have an nnml group locally and I want to
"share" it with myself via IMAP, a Group-level command
should migrate everything from the nnml group to a new
nnimap one, without losing state.

Yes, please.
