    Sadly, I knew what you meant and retyped the wrong interface name anyway!
    As for waiting for all references to be released, that won't happen, as the
    Client App holds a reference to the object to keep it alive.

    That could be done, as I implement window.external myself.

    Anyway, it just seems like a lot of work for something that I thought would
    be easy... I should have realized that nothing is ever easy...

    What I have done for a workaround in the meantime is a similar principal- I
    created an in-process server that fires all the same events and the User
    object. It has a method "Connect" that takes a User object as a parameter
    and sinks all of its events. All this new object does is re-fire any events
    that the User object sends. I can then create this server on a page with an
    <OBJECT> tag and sync its events using the standard "Object_Event" style,
    which in reality is the same as sinking the events of the User object
    itself. Very roundabout, but much easier than reimplementing the User
    object and Browser container...
