Wearing my Paradigma hat here - that pretty much sums it up, but the key is
actually knowing for certain if what you have in mind qualifies for free -
they revised their license after SQL 4.x which eliminated a lot of what was
considered free before. 

mySQL AB has done a thorough job of stating that any potentially commercial
use, you are going to have to pay their commercial fee. This was considered
very carefully in pricing Valentina.
