RE: best way to create entropy?
I know that a popular method for generating random bit streams is to take radio (stellar) noise and convert it into a digital bit stream. Very popular among crypto geeks.

Personally, I've used and recommend this USB stick: http://www.entropykey.co.uk/
Internally, it uses diodes that are reverse-biased just ever so close to the breakdown voltage such that they randomly flip state back and forth.
