    Ozone is looking interesting. From their docs:

    "ozone is based on a central activation architecture. Objects never
    leave the server for any reason. The client applications control their
    objects in the database via ozone-RMI.

    "This architecture has advantages but also disadvantages over systems
    that activate objects in the client. ozone is better for applications
    where the data are frequently changed by different clients.

    They mentioned transaction controls, too, although I haven't seen them

    Key features:
         multi-user, multi-thread support
         object level access rights
         fully transaction based
         explicite transaction demarcation via JTA (what's JTA?)
         deadlock recognition
         BLOB support
         XML (DOM) support
