What I don't understand is this demand to integrate technology that many don't fully understand, is still bleeding edge and untested, and also doesn't overlap with any of the current business objectives of your current ecosystem. Ethereum is totally different from Bitshares. Integrating it doesn't add value to your ecosystem, it just distracts the developers from building a STABLE CLIENT AND PROTOCOL as well as demonstrating your core value proposition (you know that BitUSD stuff) actually works and is ready for mainstream adoption.
There is a much better technology for chains seeking to add smart contract functionality namely codius. Also you should consider OT as you have an ample supply of delegates to run the tech. But by all means, like Kim Dotcom, go chase the hype at the expense of execution and credibility. The project has already blown 4 million dollars, why not another 4 or so?
