It depends, obviously. There's plenty of space on the screen to
display random stuff (a 80*25 xterm window with .5 bits of entropy per
character is enough for our purposes, and thus other software can
easily be used to gather randomness) -- of course you cannot expect
good output if you simply start up X and do "xwd -root" for your

Surely that would be better, but we have to expect /dev/random-less
machines to stick around for quite some time. The existence of
/dev/random is nothing software should rely on; there are many OSs,
and not everyone will be willing (or able) to switch to newer versions
or other OSs to have /dev/random.
