Build your Wi-Fi app from an out-of-the-box Wi-Fi module?

Here's an idea for your next YC app: If any of you are thinking about building devices based on hardware, consider using an out-of-the-box Wi-Fi module from GainSpan. Unlike most Wi-Fi modules and chips you see in the market today, GainSpan has optimized their chips and modules for low data-rate, low-bandwidth devices. Think Wi-Fi thermostats, Wi-Fi blood pressure monitors, Wi-Fi enabled treadmills, etc. Note that these applications are the ones that can leverage internet connectivity for monitoring data and controlling some data parameters. There are tons of possibilities for apps that can come out of these modules.
