Virtual Vegas - Steemit Style

I'm not aware of any online gaming sites that accept Steem or any other cryptocurrency but I believe it would be an amazing leap forward for the digital currency space if an online casino or sports book accepted something other than USD or other fiat currency (pick a country). Is this feasible given the time it takes for transactions to finalize or would you have to fund an account using the digital currency and play games in whatever currency the house creates?

Perhaps the casino takes in fiat and pays out in crypto? Thoughts?
