Architectural Question on Remoting and UI Integration

I have an architectural question concerning the integration of UI elements
from one application domain into another. The context of the question is
related to dynamically loadable/unloadable plugins which contain UI.

While it is possible to load and interact with forms belonging to another
application domain, is it possible to integrate them into the user interface
of the current application domain?

Example: An application has a form with a panel that is used as a
placeholder. The application loads a plugin into a separate AppDomain. The
plugin has a form we wish to load into the placeholder as a child form (i.e.,
add to the placeholder’s Controls collection).

My current research leads me to believe this is not possible. I get the
error, “Remoting cannot find field parent on type X”. It appears that
Remoting cannot access private members properly across the context boundary.

Can anyone iconfirm this is true, or provide some general guidance on how to
solve this issue?
