[Tilecache] Google Maps with Tilecache

[Graham Davis]

Hi,

I'm looking into using Tilecache to manage my own Google Maps overlay 
layer (using the Google Maps API client and not Openlayers).  The little 
information I've found online about this is that I might be able to do a 
TMS request to Tilecache if I can invert Google's Y index value (since 
Google maps has an origin of the top left instead of the TMS bottom left 
origin).  However, I haven't been able to figure out how I can find the 
Google Maps "maxYTiles" value for a given zoom level within their API 
(as you describe doing here for Openlayers:  
http://www.nabble.com/Re%3A-Nasa-WMS-Tile-server--p7896862.html).

Basically my question is, do you know if I can use Tilecache to serve my 
own custom layers for Google maps, and do you know of anyone or any 
project that has done this already?  Do you have any examples or 
suggestions on using either a TMS or WMS request from Google Maps API to 
Tilecache?  Any insights would be appreciated.  Thanks,
