I have been experimenting with melee, and although atm I am focused more on setting up a couple of utility teams in efforts to get ready for WOTLK, I will be working more on this team in the future.

Ughmaheadhurtz has also done a fair amount with 5x enhancment shamans.

One last thing I want to mention about using multiple melee is that if you are considering starting up a team I would recommend using tauren as followers and anything else other than tauren as the main. The reason behind that is that Tauren have a 9yd melee swing as well as a 9yd melee hit box.
