Apparently I didn't strip all I could strip from the previous example.
This is the bare bones of the problem: the last line returns false
instead of the expected true.  Am I misunderstanding something basic
about the way DRb works?  Maybe passing ``self'' in Client.login does
not really pass a reference to self, so it does not match when it is
later compared in Client.online? ?

#!/usr/bin/env ruby

require 'drb'

class Client
  include DRbUndumped
  def initialize(server_uri)
    DRb.start_service
    @server = DRbObject.new(nil, server_uri)
  end
  def login
    @server.register(self)
  end
  def online?
    @server.online?(self)
  end
end

class Server
  def initialize
    @users = []
  end
  def register(user)
    @users.push user unless @users.include?(user)
  end
  def online?(user)
    @users.include?(user)
  end
end

DRb.start_service(nil, Server.new)
client = Client.new(DRb.uri)
client.login
puts client.online? == true
