I'd appreciate it if you could investigate a bit further.  The code I
was referring to is at

http://bazaar.launchpad.net/~stefanv/supreme/main/annotate/head%3A/supreme/misc/io.py

As you can see, it is very simplistic.  It also returns a bunch of
Image objects, that we don't need.  But the basic idea is there: a
container over which you can iterate, that loads images on demand and
keeps a cache as necessary.  I've never played with loading of
multi-layer images, so I hope you can get something going.
