Perfect-pouring teapot

I am yet to encounter a teapot that pours without dripping (at some level of fullness of the teapot and hence angle). I suspect the reasons these are an engineering challenge have something to do with fluid dynamics, surface tension and potentially the water molecules bonding to the surface.

I watched recently an amazing video from Ross Nanotechnology of the NeverWet superhydrophobic spray-on coating (I would recommend watching the video), and it seems to me that this coating in the spout of the teapot has the potential to prevent dripping problems. As the water would be repelled by the surface, it wouldn't hang around to create a drip.

I hope their spray is suitable for food-preparation uses!
