Is this gambling site still actively paying out? Could you provide proof of withdrawals and possibly the amount of BTC in reserves? This way, we can be assured in case of a big payout you'd still have enough funds to continue running the service instead of a ditch and run tactic.

On a side note, has anyone reviewed over the fairness/legitimacy of the hash, client and server seeds? Is everything what the OP mentions regarding the model as legit as he claims? Just want to make sure no funky code running in the background in favor of additional house edge.
