dRuby for Penetration Testers

I like Ruby somehow, a nice and shiny programming language. At some point last year, I decided to have a closer look at 'Distributed Ruby' (also called dRuby). dRuby is all about easily usable objects and method invocations over the network.
So no long words: let's just drop into some simple dRuby server code: 

01 require 'drb/drb'
02 URI="druby://localhost:8787"
03 class TimeServer
