I know there's already a video poker game on there (https://www.vegascasinobits.com/videopoker). So it is possible.
did you try his game? http://pokerforbitcoins.ddns.net
if yes lets assume he wants to set it up like a regular video poker game as he is providing it.
could he offer this kind of game with Moneypot?
Well, I suppose I could integrate my game with Moneypot. But I actually have a system for bankroll and transfers and I could make a provably fair system too.
There's a different concept too: the idea of pokerforbitcoins is that you don't need to register or login or nothing. You just enter a bitcoin address to collect your prizes and start playing. I could also offer my system for others who want to develop their own front-end and make use of this system for managing the coins and the cards. I just need to develop a simple provably fair system. I'm thinking on a secret key renewed each 5 minutes and a hash from the utc time, so anybody could check the origin of the choosen cards.
