To help people who need this, I'm thinking of releasing KeyAngel, a locally-running vault that would effectively put a robust time gap between a configurable Bitcoin private key and yourself, which can be a very useful tool for curbing gambling addiction. It would be one of those really simple apps designed to do one thing well. Is anyone interested?  

Note: There is no perfect solution to the time vault problem, each approach has some benefits and drawbacks, but my goal with KeyAngel was to make it robust enough to help users enforce their decisions, while not requiring to trust any third-party website or service. All source code would be provided to interested users, of course.

I am also open to suggestions and opinions from gambling site operators.

Shoot any questions or comments here or by PM if you are interested in this. The app itself is fully functional already, and I and a few friends have been using it with great success, but since my free time is extremely limited, I will only make a more simple GUI and further develop the app if there are enough interested users (say around 25-30 users for a start), or donators are willing to fund the project.

Note: feel free to post or PM me from a sockpuppet account if you're a "whale" and would like to remain anonymous.
