    Cool, I have been pretty busy catching up, with work since WWDC. However, I
    spent about 12 hours working on it this weekend. I spent most of yesterday
    just trying to get the 3t stuff working. I ran into the error 500 with
    Hessian 3.0.20. I finally had to track down a 3.0.13. But I got it going
    late last night.

    For the CoreData stuff, I have written the following:

        Extended
            NSManagedObjectContext - which should encompass faulting
            NSPersistentStoreCoordinator
            NSManagedObjectID

        Created my own classes since these aren't exposed by CD
            ObjectStore
            TransactionalObjectStore
            CayenneObjectStore (I am just starting implementing this)
            WebObjectsObjectStore (Planned for the future)

    All of the above have not been tested yet, since they all work together.
    Hopefully, I will have some time this week and we will get to integrate it
    all together with the stuff that you have been doing.
