That doesn't have anything to do with the server side if I am not 
mistaken as you should receive that via the browser that actually 
allows you to receive the mac address -via an extension- or some 
private API exposed by the browser.

I don't know the use case but you may be better off with browser 
fingerprinting if you'd like to have a unique way of identifying 
the visitors. Or, if it's a local network, maybe you can use 
tcpdump/libpcap.
