Hello, my name is Delyan and I am experienced Action Script 3 developer. I have an idea how you can implement similar code in you flash banner. I think you have a variable declared in separated xml file on your server for example, and set the banner to lookup for this variable every time it is executed. When you change the variable in the XML this can change the banner behavior. I am not sure is it going to work on the 3th party server, they may have some request blocking or something, but you can try. Please check my reviews and contact me if you are interested.
