db/db may be a huge object that you wouldn't want sent across the  
wire, or its a lot of code that doesn't need to be loaded.

A) DRb tries to marshal objects when communicating.  If DRb can't  
marshal the object, it sends a DRbObject proxy instead.

B) When DRb is trying to send marshaled objects back and forth, both  
sides need the class definition or the object needs to be undumpable.
