   Wow, that will be very handy!  Thanks!!

   I think a two-way sync would be useful functionality to have,  
perhaps tied to a command line option, at least for the sake of  
completeness.  It would also open up possibilities for having an  
"offline" IMAP server, which might be useful for mobile workgroups  
and such that may not always have full connectivity.
