Acebusters is currently conducting a crowdsale for their online poker solution built on ethereum.
The very interesting part for me about their solution is the fact that they are trying to solve some of the poker governance challenges with crypto economic principles.
Some of these look similar to the design of the economic incentive of steem. They also have power, which is powered up Nutz (their inherent currency) in the same way steem power is locked away and provides income opportunities and gives voting power.
This is then used to prevent people from cheating in a similar way steem power prevents people here from being succesful when posting bad content.
Listen to Johann explain the design and advantages of their solution.
