Things in the world of computer card decks are far more complex than one might imagine.

Absolutely nothing is known about the cards prior to them being dealt.

It's the actions of each and every player that feed back to the randomizing algorythym the information it needs to make the next random choice.

The players actions are timed to the microsecond, and those timings are the key data for the computer deal.

Because people all dwell on their cards for different times, and because there are inherant latency issues with the internet, there is no way that anybody can predict what the randomizing algorythym will do at any given time.

I supose any computer application can be defeated though, so it all comes down to their security and their will to secure their poker sites from other cheaters.

Yeah you would have to access the code from inside, which would be possible. I really doubt that a owner of an online casino would risk the reputation of the casino when he is already making so much money. there is really no reason for him/her to put in the extra time for just maby at the most 100 grand. online casino make millions without breaking a sweat.
