MySQL synchronize with MS ACCESS

[_LOBO_]

Hi
I've just set up a new website using php and mysql.
In our office we run a access database. We would now like to
synchronize access with mysql.

Further there are plans to synchronize multiple access databases
over the internet or a dial-up connections.

Does anyone know a good tutorial for these topics?
Any first-hand experience in synchronizing online with offline
databases? (and offline - offline through the web)

Thanks
