New Wi-Fi Spec to Permit Direct Device-to-Device Linking

I believe the ability for Wi-Fi devices to connect directly to each other has been there since the beginning: this is called ad-hoc mode. (Most of us use the infrastructure mode, when the devices talk only to the access point, which acts like a wireless switch.) It sounds like this spec is all about making the process of setting up an ad-hoc network between any two devices easier and more transparent to the user, which is why it's just a software upgrade. It's kind of like WPS, which is a software feature that makes it easier to add devices to a WPA-enabled infrastructure mode network.

So it means that we can link with Wi-Fi with another Wi-Fi device like the NDS?

Add wi-fi to Bluetooth internet and you could tether a computer anywhere without wires. I like this possibility.
