Something like distributing files with encrypted data in most columns
can be done, with the encryption key being a combination
of some hardware-related stuff such as MAC address that the user will
provide to you, and the key you generate and provide to the user.
Of course it creates a problem when the target computer crashes.
Everything else is probably either hackable or would be based
on the assumption that you'll be in the business forever
but anyway there must be specialists out there in some security related
groups that know how to make it hard to hack.
On the surface of it if you provide this sort of protection you'll be
able to distribute
it as open source since you are protecting data and not the code but
I'm sure bigger lycensing minds will easily prove me wrong and explain
that there is such a thing as a GPL for data and copyrighting data is bad,
which would mean that copyrighting anything is bad, or that copyrighting
data is OK but the essence of your application is data so if you charge
for it you can't distribute mysql with it under GPL etc.
Actually it would be interesting to hear the opinion of mysql legal
department on this.
Thanks,
Michael
