Just to add to the confusion... there is a project called MyWMS which 
has been implemented by Klaus Benndorf (all in German: 
http://www.bt-gis.de) in cooperation with MySQL AB.
There is a case study (very short, German language):
http://www.mysql.de/it-resources/case-studies/mysql-bt-gis-anwenderbericht.pdf

It states that MyWMS is OGC WMS compliant (it probably should say 
implementing) and uses some MySQL "spatial operations".
The proprietary forerunner GISeye contains a very powerful rendering 
engine which can handle the cartographic wilderness that German 
cadastral maps boast (Steve added some of this functionality to 
MapServer last year). It will be (was, is) released under the GNU/GPL 
with a dual licensing simliar to that by MySQL AB.

i did not yet have time to dig into it. If you are interested in 
internal details of MySQL spatial functionality probably Klaus will know 
best.

Best,
