computer perfect play for online live dealer games

It occurred to me that a computer perfect game might be a way to make money in online games with live dealers. The program required for such a game would be quite simple. All the program has to do is start with an entire shoe, then enter the rank of each card dealt and subtract that rank from the shoe array. The computer would then have to model the various game possibilities given the remaining composition of the deck, and would have to be able to make smarter hit / play decisions. The computer could also simulate the current composition of the deck and more clearly determine the advantage or disadvantage of the player.

Am I right in thinking that a computer-perfect game will give the player a good advantage, even with not so much penetration? If you could get over the top, say, 2%, then you wouldn't even need to risk such a large amount of money in terms of a trip roll on your hands in case the casino decides to ban you and confiscate your funds. Or am I overestimating the advantage of a computer perfect game? It seems to me that a computer should be able to calculate changes in advantage much more accurately based on deck composition through simulation than any crude counting system can hope to achieve, especially when you count on the ability to make much more accurate hit decisions / rack / double. Or is a weak penetration enough to stifle even the most agile mechanical mind?
