of MySQL, you are under NO obligation to reveal the source code of the
application you develop which uses the database. The only "reveal" obligation
you will have is if you modify the MySQL source code itself. That is a
reasonable requirement of the license.
This little thing was omitted from the post on CF-Talk, and I caution anyone to
takes the post literally to mean that your application which uses the database
is automatically open source as well. It just ain't so.
No user should be afraid to use proprietary code to access a MySQL database
