In my opinion this is THE biggest announcement that I?ve heard from Adobe since the release Flex 2 in the Summer of 2006. This is bigger than open sourcing Flex. This is bigger than AIR. Here's the news: Adobe is open sourcing AMF protocol and messaging under LGPL V3. Christophe Coenraets, a Senior Flex Evangelist from Adobe, told me about this new free product called BlazeDS. While many people are using Flex for creating cool widgets that can make your Web page prettier, enterprise Flex developers have to deal with such boring things as bringing data to the client. And they want to do this as fast as possible. AMF3 protocol allows your Web application to send the data over the wire at lease 10 times faster than a regular HTTP.
