Random numbers

So figure you want more than 56 bits of pure unpredictability as your seed. This is a tricky problem. One option is to give the user a typematic buffer: "hit keys for 30 seconds" - you NEED unpredictability!

So, it sounds like what we *really* need is a little box with a shot-noise generator that attaches to a serial port and generates truly random numbers to use for the key. Anyone out there feel like designing one for us ?

Last time I was fingering through an analog parts catalog under the telephony section I noticed a bunch of parts that generate audio-noise. Maybe some of these would be suitable (if they dont use an internal digital state machine to generate the noise).
