Firstly all the luck in the world with your endeavour. If it wasn't for podcasts all I'd listen to would be the WoW soundtrack! Have you heard any episodes of Ctrl Alt WoW (http://ctrlaltwow.blogspot.com/). The presenters all multibox to a lesser or greater degree but don't go into too much depth as to the mechanics etc. Might be worth checking out though for 'inspiration'...
