You make some good points, and I now think I understand the problem.

As to your last point, my desktop to server link is only secure for a
certain definition of secure.  Actually, it's insecure, plain IMAP
over the public internet, but I happen to know the route it takes goes
through only nodes which I trust.  My server doesn't support IMAP over
SSL, nor can I tunnel over ssh.  So I'm slightly constrained.

Thanks for your input.

cheers,
Simon

PS: What I have actually decided upon is to keep a separation on the
laptop of desktop from server, by means of folder prefixes.  So I have
some duplication on the laptop, offlineimap is happy, and so am I.
(Of course, I'd be happier if the sysadmin of the server would support
SSL or ssh.)
