You can only push data "on demand" with Flash Remoting. You cannot control when you'll get the response from a remoting call... (you'll get the response as soon as the request is finished on the server). It is a request/response mechanism.
If you need to be able to push data from a server to a Flash client in REAL TIME, you'll need to open a socket connection on your flash client (with XMLSocket() object). On the server side, you'll need a socket server to handle those connections (for example Unity from www.moock.org). But, you'll have to handle the interaction between the socket server and your CFCs. For example, you could write some java class that will call your CFCs and return XML formatted data to your Flash client. So, it is possible, but it requires quite a lot of coding... In fact, the easiest way to do it is to use Flash Communication Server MX and it's remote Shared Objects (more info : http://www.macromedia.com/devnet/mx/flashcom/articles/whiteboard_3.html). On the server side, you would write the Flash Remoting ActionScript that will call your CFCs and populate a remote Shared Object. All the interaction with your CFCs are on the server side, between FlashCom and ColdFusion. As soon as the remote shared objects is modified on FlashCom server, all the Flash clients connected to this shared object will be automatically notified ("onSync" event). FlashCom hides all the complexity of the socket connection and notification mechanism. It's really great!
