ah, in the initial snippit, I assumed you were starting the server with
Distributed, rather than its inner class.  You will need to use it for a
case like this:

------ server
require 'drb'

class Foo
  def bar
    return Bar.new
  end
end

class Bar
  def foopy
    "foopy"
  end
end

DRb.start_service(nil, Foo.new)

puts DRb.uri

gets

------ client

require 'drb'

DRb.start_service
foo =3D DRbObject.new(nil, 'uri')

puts foo.bar # <=3D works
puts foo.bar.foopy # <=3D NameError, unless you include DRbUndumped in Bar
                   #    then its "foopy"
