This is pretty cool. Interstingly enough we developed a similar system internally. Without more details I don't know how their analytics work but I'd recommend that they patch into Google Analytics in some way. If they had a system that automatically created the custom segments and let me analyze the data I want in GA that would be incredibly powerful.
