[Tilecache] TileCache tile storage questions

[Xiaoyuguan]

Thanks very much,Mendes.
The idea of store tiles in zip format is saving disk space, right now we have disk space problem. Because a lot of tiles are too small,even smaller than one file cluster. If we can store tiles as one file, that would save a lot of disk space. 

I read tilesize doc v2.1. In the doc, it says tilecache support mbtiles and amazon cloud storage.
