Most lighting control that's out there is serial because it was developed several years ago for home automation systems that only communicated serially. Upb x10 and several others use it. The powerline adapters used for these are serial. All they would have to do is make the adapters with a network interface but their main market is home automation. The newest versions coming out usually are tcp/ip or udp based, so I'm sure there's a lot more to come, but right now there is a HUGE serial controlled installed base.
