Creating Google Tiles with MapServer?

Hi,

I want to create a cached base map from a large geographic area.

The base map file on my MapServer contains about 100 GeoTIFFs of aorund 
1GB each. And will be containing more in the near future.

I want to tile the map at several scales for improving performance 
(although probably NOT at all scales!).

It seems to me that using the Google Maps tiling scheme may be the best 
thing for long-term compatibility (who knows how I may want to use these 
later on).

Does anyone have some code to slice and dice from MapServer to a local 
or server cache? I've seen bits and pieces scattered around, including 
tools to match up the maps, but most seem geared at smaller map sets. It 
would seem that Google Maps has an established Lat/Lon to x/y values for 
their tiles and that a tool like that would not be necessary coming from 
MapServer.

Thanks a lot,
Kirk
