Personally, I would prefer AMF to Websockets. But then again, it's not a what the developer wants, it's whatever meets the business needs. When there are a bunch of Websocket servers out there, I imagine it will be adopted by Flex. Until then, why bother?
Isn't AMF just a way to serialise data in a binary fashion, somewhat akin to Caucho Hessian?
Doesn't it still sit on top of an HTTP protocol?
Websockets reduce the traffic over the wire by removing a load of extra HTTP header 'fluff' after an initial handshake.
What I'm saying is this should be the new ws:// or wss://
Yes indeed. I guess I misunderstood what WS is. Once WS is wide spread enough on servers, we will probably see some 3rd party libraries out there which implement it using sockets in flash. I doubt we will see it natively implemented in Flex until there is a large demand for it.
