I'm sure once the demand is there, the silicon will be mass produced. I like 38khz modulated IR more than 115kbps, you can get really good range at low cost and power, without high parts count, and if you have large amounts of data rather than just stuff that takes advantage of directionality, you can do it over Bluetooth for cheap. Never got a chance to play with 115kbps though, seems like it could be pretty cool, but I'm not sure what I'd do with it.
