Wes,
I'm working on an integration with Amazon's web services. My work is based on tDOM, which makes life a lot easier. Take a look at http://www.thecodemill.biz/amazon for an example. This page will show basic book information for a (fixed) book. All the data is obtained through Amazon's web services. At the bottom of the page you'll find a dump from response from Amazon parsed by tDOM. All repsonses from Amazon are cached too! Expect to hear more come January.
