In that respect, it is turning the local multiplayer into an online match. It's probably a lot of work, but I always wondered if maybe a console such as the dreamcast used in conjunction with custom pc software could do something similar. Might need some extra hardware... something to translate the incoming controller input data coming through the internet to a controller port.
Also, back in the 90s on the 16 bit systems, a third party developed a modem and reverse engineered several games such as Mortal Kombat, to be playable over dial-up internet. As I understand it, you plugged the regular version of Mortal Kombat (with no online functionality programmed into the rom) into the modem cartridge, and you could do online match making. That must have been a similar concept to sending controller inputs through the internet between two consoles.
