synchronizing gnus sessions on multiple computers

[Roland Winkler]

In my work, I am alternating between two computers where the user
directories are complete mirror images (updated via rsync whenever I
need to switch from one to the other computer).  Somehow I am having
difficulties to get this to work with gnus:

- How can I tell gnus (in a running emacs session) that I've rsync'ed
  all local user directories and gnus should update itself accordingly
  when, for example, articles are marked as read or expired.

- Where does gnus store the information that I have read or marked for
  expiration some news or mail articles in a group?

  (Somehow, right now when switching to the other computer, gnus appears
  to be becoming aware of new articles that arrived on the other
  computer and were subsequently rsync'ed to the local machine; only the
  marks regarding the status of these articles are lost when switching
  to the other computer, as if these marks were stored in a file that is
  ignored by rsync.)

I hope that such a work flow is not running into fundamental
difficulties.
