I'll look into this but my Python skills are a bit sketchy..

At this point ideas are welcome.  Originally I set up a WMS to server both a
web application and background images to GIS.  I understood how a tile
system would speed up WMS requests and created it for MapServer.  It works
fine but using TileCache and adjusting my web code to ask for specific tiles
made a huge speed increase.  Now I wonder if I could then reset the MapSever
to look at the cached TileCache images to save diskspace and serve to
traditional WMS requests (thus the need for the world files).  I don't see
ArcGIS supporting WMS-C anytime soon.
