It is normally something built into the network card.  The wireless
chipset needs to have support for it.  As I said, it is already being
implemented in wpa supplicant.

Wi-Fi Direct, previously known as Wi-Fi P2P, is a standard that allows
Wi-Fi devices to connect to each other without the need for a wireless
access point. This allows Wi-Fi Direct devices to directly transfer
data between each other with greatly reduced setup. Wi-Fi Direct works
by embedding a limited wireless access point into the devices, and
using Wi-Fi Protected Setup system to negotiate a link. Setup
generally consists of bringing two Wi-Fi Direct devices together and
then triggering a "pairing" between them, using a button on one of the
devices, or systems such as NFC.

It is?  I have tried connecting under these circumstances and nothing
remotely like this happened.
