I'm thinking of building a countdown into a limited period license. I have a license request script that could incorporate setting a timestamp. The license I send could include a number by which to set the license period. And I have an 'Activate' license script to check the license and it too be used to set a timestamp.
Main problem I see is if I also want the license to be renewable. This would mean the timestamp would need to be re-set. I assume I'd need to incorporate an encrypted date into the license? I would be interested in peoples ideas to this scenario.
