Hey marioeincarnate,
I guess usernames are truncated.
Yep. It seems you could do netplay seamlessly in a browser. The project is still early in dev, but if you're interested, you could actually already test websockets with the liner demo by modding pif.js. It may need a button array and logic to set which player is player 1, player 2 and so on, so player 1 doesn't control all active players. It'll be interesting to see how your n64 controller integration works too if you play around with it.
