I don't see why it has to be terribly expensive myself. The initial R&D costs might need a wad of cash, although probably not a massive figure when you consider the amounts of money in football these days. The actual cost of producing the equipment to do the job doesn't need to be very big at all, for many cases. For decisions involving the location of the ball/players i don't see why it would be so hard to implement an accurate and relatively cheap system. On our phones and in our cars, pretty cheap little GPS chips can tell us our location on the planet earth with an error of just a couple of metres, the technology required to tell the location of a ball and 22 men in a field to a good enough accuracy probably doesn't be all that cutting edge.
How it's implemented in the game? Give the referee live feedback on the game, and let it be a tool he uses to make correct decisions. They already have earpieces to talk to their assistants, we don't exactly have that in sunday league, do we? Why not just a few more little chips to have in their beltpacks to indicate to them when the ball has crossed the goal line, or who's in an offside position when a ball is played towards the opposition defence?
I sometimes suspect it's because bad decisions play a role in the popularity of the sport.
