- The compromise I came to a long time ago was to get the best of both
- worlds, in a sense.
-
- The license manager warns the user and the administrator of any
- violation, and sets a clock running. After 14 days, it will then
- deny the offending user the service they are not licensed for.
- This includes violations of change in hardware, number of users,
- etc.
-
- This gives plenty of time to get new license keys etc., which are usually
- available over the phone within 2 or 3 days.
-
- Solves the security problem, but doesn't leave the customer in the
- lurch unless they ignore the warnings or try to get around them.
-
- p.s. the extra benefit is that this can also be easily modified to
- allow demonstration use of the software. The same mechanism keeps
- track of demo time left (instead of 14 days, the counter starts at
- say, 60 days), and if the customer wants to buy, they call up,
- order the software, and get new license keys allowing them to keep
- their existing installation by converting it to real software.
