I need some ideas to license a filemaker database.
I want to limit the use of database on two constraints-
1. Number of devices.
2. Time period.
I can sell a license for 3 Devices for 2 Months so my customer can only use the Database within these limits.
The devices may be IPAD (preferably), Windows PC or MAC.
Have someone any idea or trick (preferably without a plug-in, because of FM GO) that works on all devices (or at least on iPAD for now on) to achieve the same?
