I just found out about SyncToy. It looks like another synchronisation tool from Microsoft.
According to the white paper, the tool is better and easier than any other file sync method from Microsoft. I will try it out in the next few weeks. The tool can be downloaded from here (thanks Kestrel200EMS).
SyncToy is available now:http://www.microsoft.com/downloads/details.aspx?FamilyId=E0FC1154-C975-4814-9649-CCE41AF06EB7&displaylang=en
