Is there a good way to sync from a server locally to iDisk?
I have data on a local server that is the master copy for several machine including PC's. I would like to sync some server folders to my iDisk on my MacBook Pro so that a) they can then be backed up into the cloud on Mobileme and b) will be locally available (and up-to-date) on my MacBook when I am off-site and may not have an internet link.

I would also like to re-sync the server to any changes on my return.

What is the best way / software to do this??
