My first macbook pro had its NVIDIA chipset broken. The MBP wouldn't boot. The 
motherboard was replace and voila, I had lost the license on some of my 
software because it was tied to the MAC address (and I could not uninstall the 
software on the now defunct motherboard). Moreover, I upgraded afterwards to a 
new MBP, and the transition was painful for the same software.

Tying software to a specific hardware configuration is BAD marketing practice. 
The customer is your friend, not your enemy. S/N tied to a name or e-mail are 
quite common in software registration and they do not penalize the customer.

Think of piracy as a form of advertisement. IMHO, when a user of a pirated copy 
(S/N here) finds your software useful, and if if the price is right for him, he 
will buy the regular version to have the upgrades, customer support, etc.... If 
this is not the case, he may not ever have bought your software anyway.

Best,
        François
