I like this idea, too, but I think they have the flow backwards.  Their 
setup will catch trash and concentrate it in the bottom of the 'net' 
which will correspond to where the outlet is...blocking flow.    The 
screen may even pull away from its catch tabs on the sides and allow 
dirty water to flow around it.  Turn it around, and the trash will be 
pushed to the sides and out of the way...where it will be held, to be 
cleaned out on the next preflight.  Once you've found it empty enough 
times to be sure your system is clean, it will only need to be checked 
when the water level is topped off or at annual.  The partially 
obstructed  will also be pushed harder against the tabs, for a positive 
lock.
