One Click Ordering From Amazon RSS

Dare wonders how to enable one-click ordering from an Amazon RSS feed. You could use the Amazon Web Services API to get pretty close. The API documents the following transaction: http://xml.amazon.com/onca/xml3?ShoppingCart=add&f=xml&dev-t=[developer's token goes here]&t=[associates ID goes here]&Asin.[ASIN goes here]=[quantity goes here], for example, using my associates ID and the amznRss dev token (because I cant' find mine right now): Ready to Die, by The Notorious B.I.G. It seems like one-click is out of the question without implementing some sort of HTML forms support in the aggregator, since one click appears to require a POST (no argument from me on that). This version of the same feed shows how this would show up in an aggregator.
