He talks about, though his time is a bit more stretched than usual, he's managed to get some real work done on the package. He gives some code examples to show off what this new development is (complete with unit tests - go agile testing!).
That bit of code is what does all the heavy lifting for me. It uses the Zend_Service_Rest component to talk to Audioscrobbler's web services, and returns the results as a SimpleXML object. Nice and simple. A perfect example of what Zend Framework is trying to accomplish.
The second code example is the tests that he's generated to check the package for errors in grabbing the 'Top Artists' and 'Top Tracks' as grabbed by the package via the REST web service.
