Another reason for letting the game wind down is that in its experimental form, the wallet is very secure, but the game requires monitoring and occasional resets to function. Because we have other projects that are taking nearly 100% of our time, it really is in everyones interest that we wind it down.
When we have the time in a few weeks to do so, we are planning on abstracting the platform out to a documented API that will allow site owners / hosts to link to their own RPC servers, and then extend the Bitcoinduit model to their own sites, where they will be providing a double hosted service to their end users. A federated model may also be applied, where games from one API key may be part of a greater round listing for all sites.
