My point is: What would you want to do with this identifier? What is  
it needed for? Which operations are made possible by knowing this  
identifier?

To David:

AFAICS there is no scarcity issue if you simply attach some token to  
some processes... But on the other hand the world isn't going to stop  
turning because I don't understand this ;-)
