A while ago I visited a game developer and have seen where he is working on. Fast starting flash games where you not only can see your own slot when you are playing. But you can also see what your neighbor is doing.  

In a year or so we will see this happing in the new slot games. And when flash allows the programmers to go fully 3D than people will have the change to walk true the casino and see al the people play at different games. You can just walk to a table and quickly make a bet on red. See other people lose and win.. hear the bells ringing when someone wins a mayor jackpot. You can meet with your friend and sit together and play on the same table.

I promise you, in 5 year time online gambling will be a different experience.
