Nested Filter Groups and Extensible Filter Support for DomainDataSource
DomainDataSource Filters should be extensible by allowing new filter classes to be defined, adding onto the EntityQuery. This would allow a custom filter to be created that uses custom logic to manipulate the query, or even have a group of filters with their own And/Or operator.

It would be great if EntityQuery supports more expressions like Contains and expression trees created with a PredicateBuilder with And and Or where clauses. This would make it possible to create dynamic filtering clauses at the client.

Also important as Toolsets like teleriks radcontrols use nested filters. Currently they have had to fork thier own domaindatasource control to support this.

Jeff this is really important. We just found out today that we cant do a negative filter. ie Does Not Contain, Does not start with etc.
