if this really will works then it will be huge. a multi-coin-hd wallet and a marketplace inside one app. you will be able to delete a lot of wallets and a lot of blockchains stored on your computer. wallet that you only have because you don't want to store the coins an polo, bittrex or other exchanges.
Also, from what I understand, the Devs of coins can add their wallet. No need to ask an exchange to list it. With all that's going on in the Us with BTC-E, exchanges are becoming dangerous. Bittrex and Poloniex are not safe. I want to move my coins to a 256 encrypted, blockchain supported exchange ASAP.
But thank you US government for assuring NVO will thrive.
