In this post on our sister site, AjaxDeveloper.org, there's some information about the slides that Joshua Eichorn has posted from his Arizona PHP Users Group presentation yesterday.

Definitely good stuff, especially since it was exported to a web page format (no PDFs or PPTs here!). He looks at some of the features of this package, how to use it (including remote classes), and some other resources/ideas to check out...
