I think for the moment you'd be under the radar in terms of answering to anyone legally. As long as you had a disclaimer stating that you were in no way laible for the quality of product sold. You wouldn't be handeling or storing any financial info, paypal would, so you'd be off the hook there. You'd be providing a community, a prt of which is people selling, and as you have no financial stake other than your own goods, I would think you're clear. Even here in the US there are some retailers whose we affiliate gets away with charging no tax because it is a web site. So there seems to still be some laxity in how the web is legislated. Of course all that could change with talks that are going on lately about who should "own and run" the internet. At the end of the day though what is in it for you? Sounds like a LOT of work with no return...other than selling your own models...Though I suppose you would get some play out of using all the other member advertising to bring people to YOUR models....hmmmm
