don't touch/modify my schemas
I don't want the data sync or anything else for that matter to "touch" any of my databases.
I also think this would be a great idea. The simplest solution would be to give us the option to tell data sync to place all the tracking data in a separate database on the same server. This would keep the schemas clean but still keep all the necessary change information easily accessible to Data Sync.

I fully agree, that is why Microsoft SQL Server 2008 has change tracking.
