MySQL Licensing Demystified

I've seen a lot of confusion lately regarding the dual licensing that MySQL uses. The MySQL website had included a clause regarding internal distribution that seemed to counter the GPL a bit and it seemed to worry people. This article mentions that the clause has been removed and contains some comments from Zack Urlocker, MySQL's vice president of marketing. It's good to see that MySQL AB is continuing to listen to their customers and stand clearly behind Open Source. To me, they stand out as a true success story. While LQ uses MySQL in a way that I know does not require a license, I am debating getting one anyway as I think they deserve the money.
