title: Python per-seat license protection
body: <p>I would like to create a per-seat licensevalidator for my python application. The python code is compiled. The goal is to prevent the costumer from sharing the application across his company.</p>
  
  <p>Basic method</p>
  
  <ul>
  <li>Create a hash-string of the system hardware
  <ul>
  <li>How to do that?</li>
  </ul></li>
  <li>I will create a signature of the hash-string (license key file) and send the signature back to the user</li>
  <li>The application reads the hash-string and validates it against the signature</li>
  </ul>
  
  <p>Maybe there is already a middleware solution?</p>
