I have been thinking about ways to create fast and responsive RIA’s and AJAX doesn’t seem to be able to cut it. Therefore I have been checking out Adobe Flex, it does seem very impressive. I read something about expensive server extensions, I’m hoping I can plugin our own backend to work nicely with Flex otherwise I may have to stick with AJAX.
One awesome thing I read about is the ability to open Sockets with Action Script, and transfer data in any format over TCP without using HTTP, even compressed data. I wonder what advantage that would give exactly.
