Damn I wish I could make it to this kind of thing. Sounds pretty complicated to set up.
I'm wondering about the switching panels. Do you have those built already? I'd like to see some pics of how you are doing it. Maybe you explained it well enough, and I'm just too hung-over/dehydrated/overworked to grasp it. :/
Thanks, and good luck! Sounds like it's going to be a great time.
