Actually, I would love to see TPEL code a web page that displayed the MAC
address of any computer that requested it. However, it's impossible for
him to do it! He does not have the ability to code such a page. He
couldn't even manage it for the satisfaction of proving me wrong!
I know that the only MAC address that appears on packets arriving at my
web server on my lan are those of my router (when a page is requested
from outside the lan), or other interfaces on the lan. Anything connected
over wireless to the wap presents the wap MAC address to the rest of the
lan.
Of course, if the OPs application is hosted on a server using some other
connection technology than ethernet, then my comments about ethernet
might not apply, but to the best of my knowledge, most servers operate on
ethernet connected hardware, and it's a fairly fundamental fact of
ethernet networking that ethernet MAC addresses do not generally travel
past media segment boundaries, such as routers and waps.

psst Thomas, prove me wrong, code a web page that displays the MAC
address of the computer requesting the web page, and post the code to
prove you did it in php. Because I say you can't do it!
