How to use WCF Data Services over SQL Azure Federation?

Question

Is it possible to use WCF Data Services to provide CRUD access to an entity that is stored in a federation member on SQL Azure Federation?

Assuming the federation key is stored in the security principal and is readily available in the application context, is there a way to intercept the service operations and issue the appropriate USE FEDERATION commands, opening the connection at the right time, as one would do if explicitly developing for ADO.NET Entity Framework?
