And crack cocaine is free, rainbows are always in the air, and there is peace in the middle east. I just read that licensing provision. Whomever wrote that was high. By the logic they've presented, they're breaking the GPL by offering a non-GPL license version of MySQL that will install and run on a Linux operating system. The Linux OS is GPL software, therefore if MySQL is able to talk to that software using the GPL licensed methods and syscalls that Linux provides, it is a derived work of Linux and must also fall under the GPL. Installations using GPL MySQL code may continue to do so, but any installations using the commercial license must cease using the software and uninstall it.

Scripsit Martin Koegler [EMAIL PROTECTED] At http://dev.mysql.com/doc/internals/en/licensing-notice.html MySQL has put a descrption of their network protocol, where they force programs using this protocol to be GPL: The MySQL Protocol is proprietary. The MySQL Protocol is part of the MySQL Database Management System. As such, it falls under the provisions of the GNU Public License (GPL). I am unaware of any legal theory under which a _protocol_ in itself is subject to copyright. A protocol might conceivably be *patented* in a sufficiently insane jurisdiction, but there is no way that *copyright* can prevent people from implementing the protocol. Hence no copyright license such as the GPL is needed. Because this is a GPL protocol, any product which uses it to connect to a MySQL server, or to emulate a MySQL server, or to interpose between any client and server which uses the protocol, or for any similar purpose, is also bound by the GPL. This does not make any sense. The GPL is a text that describes conditions under which certain software may be _copied_ in original or modified form. It does not speak abot a right to implement a protocol, nor does it purport to grant such a right subject to an conditions. Therefore if you use this description to write a program, you must release your program as GPL. That is at best a horrible misunderstanding, at worst an outright lie. -- Henning Makholm ... not one has been remembered from the time when the author studied freshman physics.
