The Microsoft Sync Framework and the SQL Services guys has teamed up to produce some rather intressting incubation projects the first one is "Codename "Anchorage":
We’re evolving the popular SyncToy application to enable much more than just file/folder synchronization between PCs! With this project, providers will be able to register and be discovered in a variety of sync groups including contacts, files, favorites, videos, as well as synchronization across services such as the Live Mesh, PhotoBucket.com, Smugmug.com, and more. Powered by the Microsoft Sync Framework - this E2E and hub for sync providers has value for both consumers AND developers...This project aims to provide syncronization between services. It's a provider based model that allows us to create so called sync groups to allow for greater flexibility when dealing with multiple sources and heterogenous data. At first glance I looks like this should really be integrated with Live Mesh.
Unfortunately the download link is still not public so I guess we will have to wait and see what gives, I'll probably post some more on this topic once the bits are available.
