Are you using Entangled? I've looked at doing the same thing, also using colored coins. But it's going to take a lot of work + luck to go up against someone as well-monetized as Ripple. Plus, the technical issues are not even the biggest challenge, it's forming and managing a clearing house in a decentralized manner. I'm not sure it's possible. But someone has to physically conduct the exchange of dollars, euros, or bananas. Otherwise, you've just developed a p2p version of localcoins.
