Really good article. "Because not everyone can enjoy an abundance of hardware, I offer you MySQL 5 Replication Playground, where all the nodes are in the same box, and they just use different ports and sockets to simulate separate machines." Virtual server from VMWare helps alot in this case.

  Virtual Servers eat up a lot of memory when you want to test three or four nodes.
  Abundance of hardware includes RAM in a single box. If you have plenty of RAM in your desktop and you can afford to fire four virtual machines, good for you.
  I have been using VMWare WS for 7 years. But when I need to do some heavy testing on replicating nodes, I prefer emulation over virtualization.
