Sweet.  I've done a fair bit of optimizing memory usage in 2K and XP
by pruning stuff run on startup and closing down unneeded services,
but I've never gotten RAM usage that low because I was configuring a
general purpose machine, not a dedicated one.  (The XP box I'm posting
from at the moment takes about 270MB for XP itself from a standing
start.  I could prune that more if I had to, but it would mean
compromises I'd rather not make, and since the box has 1.5GB RAM, I
don't have to.)

Along those lines, a chap on the Puppy Linux forums got a working
Puppy installation in 16MB RAM.  To do so, he had to take out
everything that *could* be removed and still have a working bootable
Linux image, and he had to actually build the image on a more powerful
machine, then transfer the drive to the ancient target system,  The
end result was a dedicated media server that performed the intended
function on a box with 16MB RAM that he had lying around and wanted to
