Maybe this solution will never work in your situation, I'm not sure.  But 
the 'unique computer name' could be the mac address instead of the 
computer name.  If not, I would expect that there is some piece of 
information that is unique for each of your machines that you could use.  
But maybe not.

I hope that one day this library will have a solution for you.
