Guest post from my friends at Adobe:
Adobe is currently building the next generation of Flex Builder, the Eclipse based IDE for creating cross-platform rich Internet applications. In this upcoming version, a significant new set of features are being introduced to accelerate creation of data-centric applications with PHP on the server-side leveraging Zend Framework and Zend AMF. Prior to the public Beta later in the year, Adobe would like to invite a select group of PHP developers into a private pre-release program for Flex Builder. You'll get to work with the new data-centric development features, interact with members of the product team, provide feedback, and generally help shape the future of the product. No prior experience with Flex is necessary; in fact feedback from new users would be particularly helpful. There is a brief survey here - please complete it and Adobe will send an invitation to you shortly.
