It was only a matter of time before more people started work on extending the LINQ structure to other providers. The lead author of the LINQ in Action book, Fabrice Marguerie created the first community one I know if to support LINQ queries over Amazon web services.
Now, Ayende (Oren Eini) has begun working on a LINQ to NHibernate implementation and is discussing it on his blog. If you are interested in IQueryable and extending LINQ, definately check him out.
If you have the time, Roger Jennings announced that he will be discussing it on the 3/29 episode of .NET Rocks.
