Create your own 100MB of Astoria Data
At Mix 07 we announced the Astoria Data Service which offers a REST based access to relational data. At that time we posted several static databases on live.com. Yesterday we enabled anyone to push their own data to http://astoria.mslivelabs.com via an experimental service.
You can easily access Astoria Data Service from any Ajax application (via the easy URL format), a Silverlight application (via the Astoria Silverlight 1.1 client library) and of course any .NET applications
