have you guys seen this yet? its the upcoming decentralised marketplace by team Shadow. Check out this vid aswell: https://www.youtube.com/watch?v=WbMpeAL95m8
its an in-wallet marketplace, fully decentral. It differents from Openbazaar because the "stores" and "listings" are actually runned on the blockchain instead of hosting your "store" from your own node (which needs to be online to access). The client also allows TOR and I2P functionality.
i think these guys are actually nailing it pretty hard with their shadowcash system aswell as it allows you to destroy your own coins and mint newly created coins leaving no history. Almost like zerocoin. Whitepaper:
