A Moka pot uses some steam pressure to extract the flavor from the coffee, whereas the South Indian filter coffee pot is more like the Neapolitan flip pot (
http://en.wikipedia.org/wiki/Neapolitan_flip_coffee_pot): with the hot water in the grounds, basic gravity is what causes it to drip-drip-drip into the resulting pot. Vietnamese coffee is brewed a bit similarly.
But some of the bigger differences are around the coffee itself. South Indian coffee tends to include a cut of some chicory, which is what they're also famous for in New Orleans of all places. And while there's great coffee in India, most people drink the cheaper powdery stuff. And yet when mixed with sweetened hot milk, it produces a great flavor I've been unable to replicate at home. One of the worst cups of coffee I made in my life was with good ingredients and a South Indian filter coffee pot.
