If you are trying to use the mac address as a hard-to-spoof security
token, forget it, it is ridiculous.  You want a smart card with crypto
authentication.  Some cheap and convenient dev kits are available from
www.basiccard.com.  Shipping charges from Germany to the US (what you
get through the online order form) are ridiculous, but there's a
distributor now in Canada now and the shipping charges from there are
much more reasonable.
