For merchant purposes, I believe URI's containing a static pubkeyhash-address are only a temporary solution until more elaborate solutions that deal with all concerns appear (tagging transactions, feedback to the merchant, making the receiver responsible for inclusion, certificates that a payment was accepted, authentication, ...). I believe static addresses are too limited for this purpose, and we shouldn't be trying to extend them with too many features. There have been discussions about more dynamic approaches (such as HTTP communication to negotiate an address) here, and I've written my own proposal as well (https://gist.github.com/1237788). The details are not really relevant at this time, but these dynamic approaches seem a much better way of dealing with what you're trying to add to the bitcoin URI system now. My 2 cents: keep bitcoin URI's simple for now. -- Pieter ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
