If you use well-defined interfaces I can't see how that would cause any higher coupling than during normal circumstances (remoting aside). A pretty common usage would be implementing the Observer pattern cross-process.

Technically it does cause higher coupling. Both sides now know something about each other. But it is really a rather academic point. /ikh
