Was reading up on SQL Azure Data Sync and found out these interesting things:

At the time of this post, SQL Azure Data Sync (Preview) does not support bigint data type.

One need to be very careful when selecting the Conflict Resolution strategy. Apparently, both Hub or Client Wins will also result in some form of data loss if the resolution is not understood properly.

Finally, I think this is the most important and missing this one out would have caused a lot of issues (and $$$) later - Synchronization Loops.
