I have two offices in one city; employees work in both of them (once in
office A, the next or an hour later in office B etc.).

They would like to have the same profile (i.e., if they log off in
office A, they would like to have their documents, Desktop, emails etc.
in the profile in the office B when they arrive there an hour later).

Is it possible with rsync to construct such a "two way file synchronizer"?

We use Samba with roaming profiles (user profiles are stored on a
server, so they can be easily transferred to the other server, but I
have no clue how to make a two-way synchronization); "roaming" the
profiles over WAN/VPN when the user logs in/logs off is out of question,
as it would be way too slow.
