This is a cool idea.

I have a question and 2 suggestions.

suggestions:
 1. provide instructions for generating EDCSA key pairs.
 2. realistic bounties based on difficulty. Obviously .11 BTC bounty for a 9 letter case sensitive vanity address is too small, While I realize this is a test, This address is probably worth something like $500USD in energy usage and wear and tear on hardware. On my macbook pro it's only going to take 1.7 years to reach 50% probability for 1DanieLRH.

Question: Have you received enough interest in your project to warrant a move from a bounty system to a  true pool system where everyone in the pool is working to generate a vanity address and then shares in the profit? The bounty method seems incredibly wasteful.

I like your project enough that I've sent you a very small donation. I hope this develops into something the community can use as a viable income resource in the future.
