NT or Win2K, lots of CPU and RAM. Runs as a service.

No clustering built-in, but I'm sure you could do round-robin DNS or some
such.

Native file system, with a pretty slick cache to RAM (you set the % of RAM
to use) that writes itself to disk on service shutdown. An XML document gets
written on the fly to manage the location of all the cached images (various
resolutions, etc.). When a jpg, or gif, or png, or whatever image is served
for the first time, it gets converted to FlashPix format for the cache...
you see a CPU spike when that happens, then subsequent calls for the image
don't even blip the CPU.

As regular files, with a mirror-image cache directory.

If you're using FlashPix, that meta-info can be stored in the same file.
Otherwise, you'll need to write your own db/CF management system.
