P.S. Maybe you weren't aware but browser based games can still be hacked. They still run on the client's computer. If it runs in Java, Flash, whatever that is still being processed on the client. You're thinking of a totally different system where the client processing is done on a remote server and only input is taken from the client, processed remotely, and then output sent back. Unity requires that client's install the "Unity Web Player" which is where all the graphics and everything are being processed so it's still on the client.
