I am so excited, I better post this before I pass out ;). Christophe Coenraets just announced on his blog that Adobe just open sourced the Flash/Flex Remoting and Messaging services under the name BlazeDS. What does this mean? Well remember all those multi-user real-time applications that Adobe demoed selling their Flex Data Services? Well now you can build ‘em for free (well, as long as you can host the app on some J2EE server).
Oh, and since AMF is a published spec now, Adobe can release the code for the Flex RPC packages (which I hope is part of the developer goodies Adobe has been promising for today).
