In the process of moving to a multitier application you could consider using a transport protocol between the layers, which is language/technology independent (like webservices, (i think tha remobjects supports that)).

This could make a reimplementation of a layer simpler later (like if you later have to make a another version of the client-application in a browser/java/silverlight).
