566661 Flash webcam script modification

Hi, I run an adult video webcam site and am looking to modify one of my flash files. The file is used to display a live video stream of a girl who is online on the homepage. It shows their video feed in a small thumbnail. I need to strengthen the security of the file. At the moment if you load the file directly in your browser you can see the live feed of any girl who is online. If you load the swf file with another model ID you can gain access to her live feed etc. That is fine however you can also see girls live video streams if they are set to "private only" mode which I need to try and stop. I am not quite sure how flash works but I was wondering if there is a way for the flash file to communicate via php/mysql every x amount of seconds to check that the model is not in private only mode and if they are cut off her pause her video feed and display a message saying the model has switched to private only mode. The current file also has audio. I would like to remove the audio from the streams. I would also like the live feeds to cut off after x amount of seconds. At the moment the video feed will continue to play until the model goes offline or the model goes into a private chat. I have attached the fla file so you can get an idea of how it currently works. I need this done ASAP. The person chosen for the job must have a strong understanding of streaming media using flash and flash media server. Thanks
