There is a good chance that you probably don't use all of the Wi-Fi that you pay for each month. There is also a good chance that you have tried to mooch Wi-Fi off of a private network at least once in your life. Now you can stop mooching and stop wasting with Key WiFi, a new service that lets you rent your excess Wi-Fi to people in need.
Key WiFi lets you sign up to list your Wi-Fi connection for rent for a small fee while those looking to connect to hotspots pay just $9.89 a month for what is potentially unlimited high-speed wireless Internet access. I could see this service taking off in crowded apartments and in businesses looking to turn a quick buck by renting out their Wi-Fi.
