Microsoft Tests 'Virtual Wi-Fi' Software: "Researchers at Microsoft Corp. have created the prototype for new Wi-Fi software that allows a user on a PC with a single network card to connect to multiple local area networks concurrently via 'virtual mirrors.'
Chandra offered other examples of how this virtualization software works. For example:
With VirtualWiFi, you can connect to a guest's machine or play games over an ad hoc network, while surfing the Web via an infrastructure network.
You can use VirtualWiFi to connect your ad hoc network, which may contain many nodes, to the Internet using only one node.
VirtualWiFi can help make your home infrastructure network elastic by extending its access to nodes that are out of range of your home WiFi Access Point."
