Just get some idea here, will WIFI replace RF in the use like X10?

Seems wireless card is cheap , even N card is under $10. Although when  I tried to search such device that I can control through WIFI, I could not find one. But I think it could be the trend? You can set such device a IP, and the way to control it is by WIFI, which is standard, that means you can control it from a software easily. Any thought?

Build it... and they will come.
