I worry about integrating more dependancies, but I assume you've taken
this into account and made this all optional.

I'm not sure I understand this? Why would you do it? I'd assume that the
WMS server -- which has the original data -- would always be in a better
position to give you the best possible image for a given bounding box.

Please:
 * Checkout TileCache from SVN
   http://svn.tilecache.org/trunk/tilecache/
 * Apply your changes to that checkout
 * If you have any added/new files in the checkout, type 'svn add' on
   the filename
 * Type 'svn diff', and send the result as a single patch as an
   attachment to the list.    
 * Fill out http://tilecache.org/ccla.txt and send the result via email
   to labs at metacarta.com. 
   
Once you do these, I'll take a look at it; looking through the existing
code for diffs is too time consuming for me, but diffs/patches are much
easier to read and more likely to be applied.

Thanks in advance!
