I believe if you grab the input your system will remain active. Call 
"pygame.event.set_grab(True)". If that doesn't do it things are going to 
get tricky.

You can detect when the application does get pushed back by watching for 
 ACTIVEEVENT. The "gain" attribute will be set to 0, and there are 
several states you can watch for. Look at SDL_ActiveEvent for a little 
more info. http://sdldoc.csn.ul.ie/sdlactiveevent.php

When your application does lose focus, you could potentially call 
pygame.display.set_mode() again and force your window back to 
FULLSCREEN. Things may flicker a bit as your program switches away and 
right back. But in the end it will be your program that wins.
