A keyword or an attribute are not sufficient.  You would need to know
which object instance to use, and you need a way to invoke the method
remotely.  A lot of issues, for which we already have an answer: .NET
Remoting. :-)

Thus, we already have a "published" keyword: the
System.MarshalByRefObject base class.  We just need a way to use .NET
Remoting via Corba.  Remoting.Corba, anyone?

The one downside is that MarshalByRefObject "burns the base class", and
Gtk# already has a required base class, so using .NET remoting won't be
entirely straight forward.

Consequently, some glue code (tying MarshalByRefObject to Gtk# objects)
would be necessary, but I don't think that would be terribly difficult
to write.

Though there is the question of why you'd want to know when a window's
destroy signal in another process was fired...  Wouldn't that be
creating a rather tight coupling between programs?  Further, GTK+
doesn't have intrinsic support for such remote signals, so it would only
be applicable to Gtk# programs, of which there is (currently) a
minority...
