Hi WipeOut, all, > http://www.mysql.com/products/foss-exception.html Interesting read: "2. You distribute all identifiable sections of the Derivative Work which are not derived from the Program" Could somebody explain to me what a derivative work which is not derived from the program means? This seems to suggest that MySQL AB believes that programs that use their database as a back end are derivative works. I would say that a derivative work of mysql is a modified version of mysql, or a program that uses parts of mysql's codebase. To suggest that a program that uses a particular database as its back end is a derivative work of that database back end is rather ludicrous. Leonard. -- mount -t life -o ro /dev/dna /genetic/research
