[Mapserver-dev] Advice requested

Hi Ned,

This sounds very cool. One of my projects I would like to get to when 
I'm not spending all my time on work is something very similar. I 
have loaded all the US Census Demographics data from Summary FIle 1 
and 3 into MySQL (about 93 GB) and want to display thematic maps by 
doing joins to with Tiger data in shapefiles. I am hoping that the 
MySQL connection will support joins with shapefiles.

I would like to see what you have done.

I think your ideas are great about abstracting your interface into a 
connection type plugin. This might also be usable to pull in other 
kinds of custom data layers and information
