See gnus-sync.el, just comitted (I worked on it last night and tested it
today).  It's harmless unless you set the gnus-sync-backend to a
filename, in which case it will start synchronizing to that file.  It's
most useful, of course, when the file is remote over FTP or SSH or IMAP
(did you know Tramp supports reading and writing files as messages in an
IMAP mailbox?)

It uses cl.el liberally.  I like the loop syntax, dolist, and setf.
