I have read that the new shuffling algorithms that most major poker sites use prevents the types of "card reading" applications that you are describing. Appearently, there was a major flaw in the old algorithm that most sites used that allowed for this. The main form of cheating these days seems to be collusion in all of its forms. However, most people who do this don't really now how to employ it properly. The one's who do know what they're doing will play higher limit tables. However, they usually can't stay on one site for very long before they're found out. The one form of cheating that I've personally encountered on Party is using the disconnect protection to show down a hand for free. The one time that I was sure I was a victim I contacted Party's support group and they promptly disabled the cheaters disconnect protection for all games.
