However, I think the logging still uses "real" TMS values when writing out,
so take a look at what images are actually being requested from the server
(in the browser).
I'm envisioning something like this:
Browser > TileCache Request Log > GoogleDisk
y=25347 y=40188 y=25347
I'm running dry on ideas :)
... Hmm, this might make sense because at zoom z there are 2^z tiles in each
column or row. 2^16=65536 and 25347+40188=65536. My bet is that if you
expose these images directly to a Google Maps API or similarly-set-up
OpenLayers system you would end up with a valid map.
