Well, easy is easy, and even "possible" means it *will* happen, so
the real question isn't technical, it's "what is the fiscal impact
of our licensing scheme being cracked?" :-)

You can generate a unique number at signup time. As Judah said, the
MAC address isn't available remotely, and obtaining it from within
the browser seems, er, problematic, so I don't believe that meets
your requirements anyway.

Unless the thing being offered is client software the user installs.
Then it's a whole different story...

Is the client's offering code or content?
