[Tilecache] Help writing new TileCache format for Virtual Earth

I have an idea that would probably be simple for you Python guys. I am using
Microsofts Virtual Earth api as my main mapping platform. I want to overlay
our wms layers on top of it. Virtual Earth has the ability to add custom
tiles as overlays. You basically set the url you want to custom tile to come
from and Virtual Earth will sent a get request with the Virtual Earth
TileName that it wants. The cool thing is that you can reverse engineer the
tile name to calculate the bounding box of the tile and then pass that into
your wms request. Here is the original article

http://viavirtualearth.com/vve/Articles/WMS.ashx   I already ported  this to
java to use with Geoserver but I thouht that it would be really good to
incorporate this into tilecache since then it would turn any wms server into
a first class tile provider to VirtualEarth.

Thanks
