title: Ruby 24/7 working XMPP bot
body: <p>Could someone help me with this? 
  I would to create a bot which receives word in one language, looks in database, gets translation and sends it back. How i understand it's not possible on shared hostings, but possible on own servers or VDS. So do i need to make my bot using libs like EventMachine and xmpp4r? If yes how to work with many requests at one time? </p>
