title: Creating a UUID for a computer from Flash
body: <p>I'm making a Flash program to be downloadable and unlockable on one computer on receipt of payment. To do this, I was looking to create a UUID for a computer which could be checked to make sure that the program has not been moved to another computer but I don't know of any way to access enough information about the computer to make it uniquely identifiable (or even close). </p>
  
  <p>I have also considered having a separate program written in a different language which would have access to this information but I don't know if I can even run it from Flash.</p>
  
  <p>Any ideas or alternative solutions to the original problem would be greatly appreciated.</p>
