The brush can be lower than the bit to get a better seal. If you use plexiglas, you'd have to hold it up too high to be effective to prevent it from crashing into your workpiece.
It's easy to make a brushed collector like the Shopbot's for flat panel work, but for effective dust collection on 3D work, it gets a lot harder.
