I can't state that it's cryptographically sound*, but if I
wanted a "comfortably random" number I'd do something like:
read a pseudo-random number of bytes from /dev/random then
pass the results through md5sum. I'd be comfortable using
rand() to determine how many bytes to get from /dev/random.
*I'm neither a mathematician nor a cryptographer; I didn't
sleep at a Comfort Inn last night either. I've read Applied
Cryptography though. There are also "true" random number
streams available on the net. One of the more interesting
ones uses a Lava Lamp as it's entropy source, others use
radioactive decay, outer-space radio noise, etc.
