License usage statistics

[ocroquette]

Hi!

Is there anyway to have statistics about the licenses usage?

What would be great to have:

• The list of moments where all licenses were in use
  
• A graph with the number of licenses used over the time
  

Without that, we may never realize the need for new licenses (if our users don't complain), and you Sparx don't want that do you?

Thanks for you help!
