I think that there are two directions that we could take (or both).
First, we could try to get ANC incorporated into the biggest open market platforms, such as OT, OB, and BXB. In the end, we would likely end up being just one of many altcoins being accepted, which is better than nothing.
Second (as suggested by K1773R on IRC), we could just fork one of these to be an ANC only platform (most likely OT). If we did this, to distinguish it from the "better known" markets, I think that we would have to go for 0% transaction fees. BitXBay (and probably the others, I haven't looked) have built in transaction fees that go to the developers, which kind of bothers me.
