Ripple stocks

[moocowpong1]

Would it be possible to use Ripple to exchange dividend-paying stocks? A company could create a "currency" representing shares of stock in their company and issue and trade those shares on the Ripple network. Is there a way of paying a dividend to all IOU-holders, other than picking a particular ledger and "manually" making a transaction to each of the accounts that holds your IOU's?

There is a feature of Ripple that I don't understand at all called "contracts"... is there a way to use these to automate the dividend payments?

Where do you see that contracts feature? Which page?
