I spoke to the developer by email, and he would like to add support for anoncoin, but for a fee of 1000 usd. I'm not too happy about paying to play. At the same time, though, the project appears to be underfunded, so perhaps this fee would go to a good cause.
I really think that it would be great to associate Anoncoin to these darkmarkets from the start. This might be a good opportunity. He claimed that anoncoin integration would take a month, perhaps less.
