ADO.NET Data Services

Been playing around with ADO.NET Data Services this morning - really cool how you can point it at your (Entity Framework in this case) data model, and it fully exposes it via a web service.

Planning on using it to replace my current MVC JSON-returning controllers.  Shouldn't be that much more difficult, it cleans up the controllers, and in the future will save masses amount of time.  What's not to like?
