[Tfug] Looking for a unique identifier

[Rich]

FlexLM and SPM are dirty, filthy copy protection software packages  
published by dirty, filthy Macrovision. They can both be set up (by  
the vendor) to use the MAC address of a license server. That's the  
only reliable unique info you can detect on Unix boxes without  
resorting to dongles and whatnot.

In the light of mutable MAC addresses, depending on your intent and  
the value of whatever it is you're protecting, you might want to look  
into Globetrotter's dongles.

Here's an FAQ: http://www.globetrotter.com/flexlm/dongle_faq.htm
The stuff about "Windows only" is BS -- I've used Rainbow Sentinel  
dongles on all sorts of Unixes.
