How to use DevForce2010 with JSON-service?

Question

I use Silverlight and DevForce 2010. My entity manager has a standard setup with a database at the server.

Now I want my Silverlight client to talk to a JSON-service and make the data-results into entities. These entities must not be saved to the back-end database server (as the other entities).

What is the right way to do this?

Do I use PocoServiceProvider and PocoSaveAdapter, and can these be setup to only exist on the client?

I was thinking of using WebClient to talk to the JSON-service and use DataContractJsonSerializer to convert results into entities.

DevForce itself does not understand JSON or REST so can't directly be used. If you want to use the entities within an EntityManager and give the appearance of db-backed entities, then the POCO approach should work.
