Cyles: Dispersion glass materal

Hello blenderheads, I am posting my test with fake glass dispersion in Cycles. What is the approach I use? First I split glass color into RGB channels which I route into three different glass closures that have each slightly different IOR. The channels are then merged back together and voila, you have something that looks not so bad.
