Probably a self reporting honor system. Sage will issue keys based on how many active employees are reported. PR will function until the day that the limit is surpassed and the system comes to a screeching halt. Perhaps Sage will give a grace period of X number of days in which to get new keys generated. I am sure the updates will not install unless the new keys are present. Sooooo, here is hoping that the key generator is much improved over the one that has been in use for the past 10 years. No matter what, the transition will not be smooth and the reseller will be caught in the cross fire.
