Sorry for this slightly OT question but I figure the audience is perfect 
and it certainly ain't a FAQ.

In Linux you can set the MAC address of an interface using "ip link 
set". E.g. in RedHat you can accomplish this setting a line 
"MACADDR=DE:AD:BE:EF:CA:FE" in 
/etc/sysconfig/network-scripts/ifcfg-eth0. This works as expected on 
real (cable) ethernet and it is also possible to use on a WLAN 
interface. BUT I have the feeling this just changes MAC on 802.3 level, 
while the 802.11b packets still uses the real MAC address.

[and yes I know you are invisible when in RFMON mode]

So the questions to anyone who can straighten this out:

a) Am I right?

b) Is there a way to change 802.11b MAC in a general way?

 - or -

c) Is there a way to do it on Aironet cards? Orinoco cards?
