I meant to say, I wrote a tiny fastcgi tile server:

It might be useful. It's a simple fastcgi thing in C to serve tiles
from openslide-supported slides to deepzoom viewers. It uses vips to
generate any missing layers. It does some caching, but you could add
quite a bit more. It'd be easy to add any extra processing you need.

Of course you can also generate the complete pyramids in advance, vips
dzsave is fairly quick.
