Right. There are ways around it but obviously all sorts of subtle
application work will go with the data, depending
on what exactly is that you are trying to protect.
Overall my opinion is that if you distribute it in a country where
software piracy is a norm, someone will hack it anyway,
in all other countries it's probably less expensive overall
just distribute it and hope that most customers will comply with the
law.
If you have competition you'd prefer people steal your stuff and not
theirs.
Thanks,
Michael

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.

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.
