MAC address = Media Access Control addressBelieve I saw that this was possible somewhere, but now that I'm looking for it I can't find the implementation.
Is JavaScript or Flash able to extract the MAC address from a browser?

The MAC address is definitely not something you can get through a web portal unless a bug exists.  If you can get someones MAC address you can change you own through some hardware/software tricks and thus make your computer look like theirs which is a very bad thing for security!
