Thanks for the clarification.  Two additional thoughts:

1) Does this apply (I think not) even if you don't compile with or  
link with the MySQL database?  If you just connect to it with ports  
or sockets, as we usually do with web applications, you still don't  
need a commercial license?

2) $595/year is still a lot cheaper than most of the alternatives  
such as MS-SQL or Oracle.

I got into this debate with our Microsoft rep over lunch about a year  
ago.  My company does consulting with a couple of large (US  
Fortune-500 companies) and unfortunately one of these is wedded to  
MS.  I work with MS-SQL quite a lot and generally find it inferior to  
MySQL and as Randy (the MS rep) was talking how you really did need  
to buy commercial licenses for MySQL, I pointed out that no you  
really didn't for web applications.  (He went on to point out what  
great support MS SQL had - I quickly agreed and said that MS SQL had  
the best support we could ever ask for... it's called "Google."   
Randy still paid for the lunch :-)
