It's more than a possibility, I have FUSE and sshfs installed and
working already, amazingly simple for something like that.  I did a
quick timing check to see how slow it is compared with a straight file
copy using rsync (no existing files so it really was a copy):-

    rsync:      3m 48.661s
    sshfs:     10m  2.824s

That's not half bad really, it's around 2.5 times as slow (this was
copying about 32Mb of maildir hierarchy, e.g. lots of small files).

I can live with that sort of speed as the backup/archiving can run as
a cron job in the middle of the night.

So it's back to mbox and then getting mailsync to do what I want
between two 'local' directories.

Thanks again for the idea.
