He specifically mentioned gamers among other superusers and said NBN Co is looking at curbing network access for popular games by throttling or limiting traffic in order to fix the problem. Which is a bit like rationing water in a crowd of thirsty people so the folks wanting a little water with their scotch don't have to wait too long.
