A clean install or parallel installs of future betas or a 4.6.2 stable will not invalidate charts.
Obviously dealing with IP protection schemes in a Open Software environment
is a mayor PITA for us.
The penalty we have to pay when licensing charts legaly.
If you add that one wants
- to serve all platforms
- being able to work and to license
- not to spy the user
- not using physical dongles as sending them around is a nightmare
then is getting even more funny(?).
We are completely open to proposals for better schemes for the Linux systems. Just drop us a mail.
What is on the drawing board is the use of the TPM subsystems that modern PCs do have. This will make the license independent from software accidents on a system. For Windows platforms TPM modules are mandatory since June last year, many older ones do have it already, although often not activated. Ubuntu is supporting TPM as well.
But don't expect this on ARM based systems.
