Hi Michael

Sorry, maybe I misunderstood the intention. Is your intention to make it 
"standard" or just to make a demonstration? If the latter, then it's OK. It's 
the first that I simply doubt it will work.

I am not claiming that there are better means to do that, let alone that what 
you proposed makes no sense. I actually said that this makes sense. I just 
think that we enter the realms of 802.1 and 802.11 at the same time and have no 
authority there.

It has indeed nothing to do with Wireless access points. Any STA (802.11) and 
any supplicant (802.1X) is subject to standardization and regulation of the 
bodies of IEEE, in any mode of operation. WPS should not be limited to any 
Access Point presence, since it supports WiFi Direct. I agree, the supported 
methods are rudimentary. If I remember correctly, something like PIN, the push 
button you mentioned, NFC and USB.

I guess, a possibility would be to specify an additional ANIMA/ACP/BRSKI method 
for WPS, why not. All I am saying is that we probably need to do it there, as 
any try to do it in the ANIMA WG would require specific 802.11 modes and 
specific 802.1X functions/behaviours, which I am not sure we can dictate to 
have.
