As Andi already said, it relies on distributions shipping the database.
The full name is "MySQL Embedded Server"; the point is that you do not need a 
full MySQL server process running, including all administrative stuff like 
user access rights, but can run this from inside your application.

Please note that we can also take a look at Akonadi, who are running a 
dedicated MySQL server process, but also probably without extra 
administration.

Yes, I think there is no Qt4 MySQL plugin that links to libmysqld.so, but only 
a plugin that links to libmysqlclient.so.
Judging from the docs:

http://doc.trolltech.com/4.5/sql-driver.html#embedded-mysql-server

it means we have to take the source of the Qt MySQL plugin, compile it 
ourselves just with the difference of linking to the embedded server libs 
instead of the client libs.
