AjaxWorld West is coming up in September. I spoke at the East coast event and I highly recommend people interested in the next-generation of Web applications to attend this conference. It's got a good mix of open-source, community and commercial RIA material and is a good venue to get up to speed with some of the latest developments in RIAs such as push technologies, offline RIAs or just plain old user-interface.
I will be giving a talk there on RIAs with PHP and Zend Framework. Joining me for this session will be Brad Cottel our Zend Framework evangelist who's done his fair share of C/C++, Fortran and Rails development (and now getting into PHP and Zend Framework).
See you there!
