Redfire - How to access/limit control?

I am using the Redfire v. 370-0.0.06 and need apply access control from my users. The idea would be to restrict a maximum of 10 video sessions. The problem is that the default URL is known and easily accessible: http://$my_server:7070/redfire/video/redfire_2way.html?me=test1&you=test2&key=se cret_key ou http://$my_server:7070/redfire/

Any idea or tip on how to implement? I’ve tried renaming the plugin folder name to a more difficult but it stops working.
