Open source means nothing if I am going to play on your servers, it be nice to know that my hand isn't being change due to an admin playing on my table or something like that. I think you should highly consider it.
You mean you want me to show everyone's cards at the end of each hand? I think that would turn most poker players off.
I see your point about not knowing what the server is running, but I think there is a basic trade off going on here:
Provably Fair vs. Ability to bluff
I'd like to put your mind at rest beyond a doubt, but I'm not sure how to satisfy both sides... open to suggestions though!
Also, on a side note:
saw a pretty cool movie called "Runner Runner", and you can see how JT solved the admin abuse on his favorite poker site!
