Start looking at "Enterprise" licenses for any of the big guys and the
pricing does get pretty scary.

On the one hand, if they are calling it "Open Source", then this is NOT
a fair statement.
On the other hand, if you look at their web site, they certainly do tip
their hat to the FUD/Paranoia about the "infectiveness" of the GPL.
They don't expressly say: "Yes, you should be paranoid about the GPL because it infects anything it ever touches with
somefrightening license virus worse than SARS."
Instead, they loudly use the line "... for users who prefer not to be
restricted by the terms of the GPL", of course, neither confirming or
denying any particular paranoia about what the impact of those terms may
or may not be.

Incorrect. You have to use another commercial product that they bolt
onto MySQL -- InnoDB, from the Norwegian company, Innobase.

Sleepycat DB was used to prototype the notion of having transactions,
but since that introduces Yet Another Continent to the set of licensing
complications, and probably wasn't sufficiently 'in their interests,'
it's not the Preferred Transactional Engine...
