For those that missed the php|symphony webcast with Joshua Eichorn, he has already posted the slides for the presentation over on his blog.

If your coming here from the php|arch webcast, welcome, and from anywhere else too. It looks like the presentation server had some sort of outage, during the question and answer period, we recovered quicly and though we lost about a hundred people, I think most people got there questions answered.

If you have an more questions feel free to post them here. The slides are available online, these are slightly different then the version in the presentation, but the content is the same, they've just had a little less editing.

It was a good talk, and for those that weren't able to attend, keep an eye out here for the links to the combination slides and audio for the talk from php|architect...

UPDATE: he has also followed up his presentation with this Wrap-Up posting on his blog, listing some of the toolkits, reasons for using AJAX, some sample PHP apps that use it, and security considerations.
