I have recently purchased very innovative software, that is currently under development.  The developer is very keen to tailor it to suit our needs.
   It will allow users to hold and type of coin they like, have multiple wallets of each, apply multisig to payments, choose any graphics theme they like, and be able to buy and sell p2p with only a public key.  The server does not hold any private key data, and if in the event of an attack, all database is backed up, remotely wiped and sms response goes to dev team.
   Security is currently being worked on involving the system of escrow between trades or bets, as well as multiple ideas of payment systems and trade arrangements.
   Users will also have the ability to trade silk for any other cryptocurrency we add, as well as the discussed usd payment processors such as perfect money, nix money, webmoney, moneygram etc.
    This is an entirely web based application currently and of course looking to move forward into mobile once developed fully.
   If anyone is interested in helping to build this project further, please comment or pm me as it is in its earliest of development stages in regards to Silk and a distributed marketplace.
