Hi aatreya,
As Scøtt mentions, Live Mesh uses FeedSync integrated as part of its end-to-end S+S platform. FeedSync and the Sync Framework are very complimentary and work well together to provide a comprehensive sync platform. In terms of understanding which should be used when, there is a simple way to think about it. If the synchronization scenario primarily revolves around variety of web feeds (RSS, ATOM etc) then FeedSync is the obvious choice. On the other hand, when the scenario involves variety of custom data types other than feeds then the Sync Framework provides a flexible approach for building custom sync solutions. So overall these two approaches are very complementary and provide a comprehensive sync platform from Microsoft.
Thanks,
Richard
