Certainly not new, I know digi.com sells a lot of these things since at least 2008. Look for the Digi Connect products. The interfaces on the other side can be as simple as RS-232.

They've been on the market for a lot longer than that, actually. But it looks like some incremental improvements have been made over the years, quite interesting really.

I remember working with several of the Parallax PINK modules back in the day as well. http://www.parallax.com/Store/Accessories/CommunicationRF/ta...

If memory serves me correctly, some peers at my university had wrote a web interface to control the lights on the Christmas Tree in the commons area.
