Blackjack Bot

Online casinos provide there own client application as a front end for the games with data sent from a server. I would like a program which sits between the casino client and server (like a firewall) and can interpret the data sent. I would like a program which can interpret the data for the game of blackjack. The data will be card values which the casino client would then display as a fancy graphic. If your program could mimic actions based on data sniffed and/or "perfect play" charts make bets, dealing, and so on and automatically click on what action that needs to be taken.
