I'd like to suggest you inventing an iOS, android client allowing to do regular commands not involving playing to be able to for example bet or host tourneys. This will totally bring more interest to the game itself, making it be much more popular itself due to putting apps in AppStore and google play. Troubles I see in it: people on one server limit and database vulnerability from ddosers.

I'd recommend to update this post for you guys to point out all the pros and contras against this to come to the conclusion about worth making this.
