The Python looks pretty decent -- no complaints.

So long as the default path avoids this code, I'm willing to integrate
it. In addition to the 'watermarkImage' parameter, I think an
'watermarkOpacity' parameter should also be made available. If you could
write a patch to the TC code, then upload it to trac
(http://dev.tilecache.org/) and let me know, I'll take a look at it
then.
