1. I don't see any pink tiles.

2. Reproject: true will not work with TileCache in any currently
   existing version of OpenLayers. Set reproject to 'false' to 
   get a bit farther. 

3. TileCache and Google do not have any currently documented way to work
   together. Some users have done some hacking -- of both TileCache and
   OpenLayers -- to make this happen. I am not one of them, and have no
   knowledge of what is required.

Patches accepted for any issues you do resolve.

Good luck and Best Regards,
