Virtual WiFi - now what took them so long?

You're at an airport. You have 5 wireless networks around. You let your pre-bundled wireless tool
pick up the network with the strongest signal (I use the Dell utility that came with my D620).

And every few minutes, the connection drops. Go to step 1 - choose network with highest signal etc...

"But mom, I thought computers are meant to save us from doing tedious, manual chores??" - well, thanks
to the diligent Microsoft researchers (http://research.microsoft.com was always one of my favorite sites), we now have the solution.

Presenting: Virtual WiFi - the ability to connect to several wireless networks through a single wireless card.
Or, as the site claims:

"It abstracts a single WLAN card to appear as multiple virtual WLAN cards to the user. The user can then configure each virtual card to connect to a different wireless network. Therefore, VirtualWiFi allows a user to simultaneously connect his machine to multiple wireless networks using just one WLAN card."

The site goes on to enumerate several other benefits of the technology:

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.

I've been exposed to this over a year ago, but this became market-ready only recently (I think it's XP only for now - Vista coming out soon).
