I am working on a product which has usage based licensing along with time. I had to store usage count into the client machine. does limelm provide a mechanism to store that information so that it is not easily changed by user? System can come online once in a week.
Yes, use custom license fields to read data, and pass new data to a script on your servers which sets the data in the custom license fields (so you have 2 copies of the data -- the accurate copy on your server and the maybe accurate copy on the client machine).
