You can't see MAC addresses over the Internet. And people can change them anyway. You can use a cookie but that only works if your target is too dumb to erase it.
You can also try a "Flash cookie" or something similar.
These also only work if you are talking about HTTP.
Basically, if a user drops cookies and can change IPs, you can't stop them.
