[gdal-dev] What do people think of the MySQL Spatial Extensions?

[Russell McOrmond]

I am aware of PostGIS, Oracle Spatial and ArcSDE.  I only became aware
that MySQL had extensions as well very recently (My brother started at
Pythian).

http://www.gdal.org/ogr/drv_mysql.html

Are there people in this list that use this extensively, and can give
some comparisons to other databases/etc?

Thanks!
