hide lock from Registered users & lock ESC key

Such an awesome plugin you have created rocksoft, congrats

I would like to know if i can add two additional features

1. To disable popup for registered users or subscribers
2. Freeze ESC key, since ESC key closes the popup layer
3. SHow the pop up only one time in a session.

With these additional features the plugin will be more wonderful, it will beat pay with like plugin..

Thanks in advance, or can you help me in modifying the code for the same..
