You should maybe also take a look at Flash Communication Server. FCS allows you to push data to ActionScript clients using RTMP; you can then just implement some kind of 'Listener' class in you client which receives notifications of data changes. You could implement your FCS code in such a way that the client makes an initial request giving its intent to listen to some server side data and then FCS pushes out the data when it changes.
Check out Client.call(..)on the server / NetConnection.call(..)on the client, or alternatively you can use SharedObject.onSync(..) and setProperty(k, v) http://www.macromedia.com/devnet/flashcom/cross_product_integration.html http://livedocs.macromedia.com/flashcom/mx2004/index.html hth dan --- In [email protected], "Mink, Joseph" <[EMAIL PROTECTED]> wrote: > Thanks, Kevin!
