Colored coins uses satoshis to represent smart property, shares, IOUs of another currency...Colored coins can be atomically traded for bitcoin. If you implement the trade across chains contract they would also be tradeable for another chain currencies like namecoin or freicoin. http://www.bitcoinx.org/ Ripple is a concept by which people that trust each other on a network are able to pay with IOUs transitively. It has a new p2p implementation that is still on development. The new implementation is very similar to bitcoin in certain senses but it has no mining. Bitcoin IOUs can be traded there. https://ripple.com/ Good luck with the implementation, this is a good feature to have, even if it's not on the main client.
