I have a question regarding "WiFi-Direct": How can I use it on Mac OS X Mountain Lion?

Background: I recently purchased a Samsung NX1000 camera which has built-in WiFi, and supports sending images via WiFi-Direct to other devices. When I try to do this while both my Mac and the camera are in the same WiFi network (my home router), the camera doesn't find any WiFi-Direct compatible devices.

What I did until now: I scoured the web for information about WiFi-Direct, obviously, but the most promising information I found were a number of articles in a tech blog back in 2009, saying it will "come soon" to Mac OS and other consumer electronic devices. Other people on StackOverflow tried programming against it (mostly with mobile platform SDKs such as Android/WP7/iOS), replacing Bluetooth functionality, but that's not what I want. I also read that the AirDrop functionality of Lion is in parts based on the idea of WiFi-Direct, but it seems they are not quite the same (confusing me further).

From the behavior of the camera, I gather there must be a way to "enable" my Mac for WiFi-Direct. Is that true, and if so, how do I do it?

Mac's don't have Wifi Direct capabilities in current version os OSX. Hence any device that uses WiFi direct (Android phones, Samsung cameras), instead of supporting AdHoc networking, will not work.

Um okay, not the answer I was hoping for, but this settles it then. Do you have any sources for this information? –  pille Apr 18 '13 at 15:01
    
Apple don't generally publish what they don't support. (I'm on ML 10.8.3) One route you can use is to go into your Airport settings icon, click "Create Network", then press the "?" bottom left. The help that appears is for "Create a computer-to-computer network", and there is this snippit: "Computer-to-computer networks are sometimes referred to as ad-hoc networks." Here is my source for the Android needing Wifi Direct and not natively supporting ad-hoc: code.google.com/p/android/issues/detail?id=82 –  Paul Hargreaves Apr 19 '13 at 15:29

I've looked at Samsung's webpage, and looked for software which might facilitate the 'WiFi Direct' feature that's briefly mentioned on page 121 of the NX1000 user manual. I did not find any software.

A common WiFi configuration (for which there are many names) is to be set to only allow a WiFi client to connect to a WiFi Access Point. Setting this feature on the access point to allow WiFi clients to exchange traffic might get something working. In the 'Sharing' preference pane, enabling File Sharing and perhaps Bluetooth Sharing might also help, although Samsung's documentation is vague as to what WiFi-Direct actually is.

(To see if you have WiFi Client to Client communication enabled, you ought to be able to ping your camera's IP address from your computer.)
