I'm debating trying to run this on The Warhorse (aka my 330MHz G4 enhanced 7500 which does run the current Jaguar, iLife and OS X/Classic apps just fine, thanks) and returning the results (wheeze). I can't prove it, but I think I have the slowest Mac here running OS X. Still, you shoulda seen it running Canon's photo stitch software this morning on some beaut 4 megapixel stills of the Canyon. Pretty quick, considering the bits being crunched.
