This is nothing new, the idea has been around for many years. The problem has always been, number one, if I make 3-4 lists that means that I have to have a lot of different things for my army to accomodate lists that are not all the same barring maybe gear. The second, is someone else is touching your models. Only if you make it invitation only will most people feel comfortable about letting whoever will handle your stuff. Then there is always the question from the promoters part on what happens when someone breaks your one of a kind hand sculpted model and it cannot be repaired. I know, I know, worst case scenario, but as an organizer I have to go there. I think the idea is wonderful and if there were enough guys interested I would certainly host.
