Thusly, yes?

Server:

	require 'drb'
	class UndumpedArray < Array
		include DRbUndumped
	end
	class TestServer
		attr_accessor :items
		def initialize
			@items = UndumpedArray.new
		end
		def add
			sum = 0
			@items.each {|item| sum += item}
			sum
		end
	end
	server = TestServer.new
	DRb.start_service('druby://localhost:9000', server)
	DRb.thread.join

Client:

	require 'drb'
	DRb.start_service()
	obj = DRbObject.new(nil, 'druby://localhost:9000')
	obj.items << 1
	obj.items << 2
	puts obj.add #Gives '3'.

Seems to work pretty well.  DRbUndumped may be the solution to my
concerns about network overhead as well.

Thanks to everyone for the assistance!
