Here a few reasons that someone may want this if they have c4: micro dimmer (client has wall sconces that the contractor added, but there is no switch, only the little nob on the bottom of the sconce)fanlinc module (client only has one power leg to the ceiling, and one decora spot on the wall... so control4 keypad, and fanlinc module)dimmable outlet (how cool is this, make the lamp dimmable, but have the outlet flush in the wall)battery scene controllers, aka portable decora keypads (why c4 doesn't offer this yet is beyond me, NYCE controls showed a drawing of one they want to doalso, the architectured (dual band 900mhz plus PLC) is really solid, and has worked well when I have used it.lastly.... price. Even with the licensed driver, which is a justified cost as it looks to have taken alot of effort, the cost saving is realized in only a few loads.
