Many users has been confused by the need to wait for the onReady event before using the Socket or Rpc instance.
Well, this requirement is now gone as easyXDM will buffer all actions and execute these once the transport is ready, and this means that you can now do
var socket = new easyXDM.Socket({
...
});
socket.postMessage("foobar");
without getting a nasty error!
