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
