Yikes!  The invitation's open for anyone to modify the product to use
ImageMagick in this way (just don't call it a hot fix :))

If that's the paramter... for me, I don't see my site ever having images
that large, since they're mostly uploaded by users TTW, and otherwise the
highest quality would be for commercial magazine print, so we only need
maybe 300 dpi.

for a really huge site, sure!  You'd have to look a the statistics of expect
amount and variation of thumbnails, etc. -- perhaps one of the other
approaches, like storing the thumbs in the image object, or manually
creating and storing thumbs, might be appropriate in those cases... depends
on alot of factors.
