Maybe... I'll take another look at it.

What I ended up doing was a simple change to  method_missing:

class ClientProxy
  #pass on any methods we don't know about to the client
   def method_missing(methID, *args)
      @drbObj.send(methID, *args) 
      #was: @drbObj.send(methID,args)
   end
end

I had forgotten about using '*' to map the array into the arguments of the 
function.
