Requirements:

1) An account created on a raspberry pi that has never been connected to the internet ever.
2) A great private key on this account, that does not rely on any random number generator.
3) The ability to sign transactions on the pi (probably a QR code will be used to get them off the pi).

I found a great solution from Vitalik himself showing how to create the account and even sign a transaction: [python_cold_wallet_instructions][1]. The line `eth.sendRawTransaction("<output of last line of code here>")` is what I would perform on a separate computer. All seems great except one thing:

The line `k = os.urandom(32)` implies using the random number generator. How can I avoid using the RNG? Isn't this a legit concern?
