Developed by military consulting firm Nomadio, Connectify lets a laptop "tether" other wireless devices to a single Internet connection by effectively turning it into a software-based wireless router. Windows 7 is required on the notebook acting as a wireless hotspot, but any wireless-equipped device, including handhelds and other notebooks running whatever operating system can jump online without any additional software. The program even encrypts traffic to and from the software hotspot using WPA2-Personal (AES) encryption.
While the Connectify beta is free to download, Nomadio expects to charge users once the complete version is released in about six weeks. A free, ad-supported version might also be released down the road.
