Phani, a data services test team member, has posted two nice write ups describing the "web friendly feeds" feature in the ADO.NET Data Services v1.5 CTP1 release we made available for download yesterday.
Also, we have created a new forum dedicated to providing feedback on "pre-release" versions of data services such as this CTP. Please direct all questions and comments about this feature to this new forum which is available at: (http://social.msdn.microsoft.com/Forums/en-US/dataservices/threads).
We look forward to hearing your feedback.
ADO.NET Data Services, Program Manager
