On server side you define empty object that ovverwrites method_missing 
and every call is transported to coresponding "real" object.

It's ugly hack, becouse proxy objects will never be collected unless 
issue is fixed in DRb, but that should help with memory usage (almost 
empty objects should not be really memory consuming)

and you can menage all the references server side.

If you are looking for better solution check packet and EventMachine, 
BackgroundRB recently switched to Packet becouse of DRb issues.
