off subject i know but here is some of the article that was written two weeks ago
Card sharing has caused major concern to the conditional access subscription card manufacturers, and their respective pay-tv companies, since virtually every encryption system can be shared, allowing unauthorised access. Unlike the hacking of smart cards, card sharing is relatively new, thanks to the recent increase in home internet speeds. Conditional access providers therefore have few counter measures to combat its use. One such method, used by several providers, is to greatly increase the frequency of changing the control word, used to decode the channel. With changing occurring as frequently as once every 5 seconds, this puts extra stress onto the subscription cards processor, meaning that clients are frustrated by short, but frequent, missed viewing, making viewing possible, but with extreme inconvenience. In response to this, card sharing servers have appeared that caches control words in order to prevent overloading of the smartcards processor if the same code word is requested more than once.
The future of card sharing is unknown, because it is equally unclear how widespread its use is. Many conditional access providers may see it unworthy to produce new cards to send to all subscribers, as their manufacturing costs are too high. Most probably also realize that and the additional "security" will eventually be circumvented anyway. The latest Irdeto cards for example, have been produced in a way by which card sharing seemed not possible, but now they can be shared again.
