Hi Chris,
I think the chances of getting a user's MAC address, using client-side
script, without them having to be prompted in some way, are pretty
remote for the reasons that others have suggested.

If you just need to uniquely identify a PC, why not use Javascript to
generate some form of GUID on the user's PC and store it in a cookie?

Of course if they have cookies switched off, or delete the cookie, or
modify it, it won't work -- but then people can change / spoof their MAC
addresses too, if they really want to...
