Re: What kind of tools can I produce for the bitcoin community?

A tool to split your wallet in two so that each half can be backed up to different cloud servers but neither half can be used to spend your coins...

you can compress and split with rar files
just tried
no unrar without both halves

Would you bet BTC500 it's secure? BTC100,000?

If you're really offering a bet, I'd be very willing to take it. It's a very simple, but functional solution.
