On the Zend Developer Zone today they've published the latest in their "ZendCon Sessions" podcast series - Distribution and Publication with Atom Web Services.

The ZendCon Sessions are live recordings of sessions that have been given at previous Zend Conferences. Combined with the slides, they can be the next best thing to having attended the conference itself. [...] This episode of The ZendCon Sessions was recorded live at ZendCon 2008 in Santa Clara, CA ... and is Ben Ramsey giving his talk: "Distribution and Publication With Atom Web Services"

The usual three ways are available for you to listen - the in-page player, downloading the mp3 and, of course, subscribing to the podcast's feed.
