I got intrigued, and managed to get something working. (It needs Flash  
Player 9.) You can try this in the Rev message box.

go url "http://www.lacscentre.co.uk/flex/socketTest/FlashSocketTest.rev"


When the stack loads, click the Setup button. It will load a swf file  
using revBrowser.

When the swf file has loaded, click its "Get Environment From Rev"  
button. Hopefully, it will display the environment variables and time  
supplied by Rev.

I had trouble working out how to manage the connection from the Rev  
side. If you want Rev to push data to the Flash element at arbitrary  
times, you need to keep the connection open. But if you also want to  
accept data from the Flash element, doesn't the Flash script need to  
reset the connection prior to sending data otherwise Rev doesn't know  
when to read from the socket. In the example above, Rev closes the  
socket each time after sending the data, forcing the Flash component  
to reconnect. Is there a cleaner approach to this?
