Hi JTxt, This is a fantastic idea for resource saving. Also streaming all the data to the clients, while possible with PubNub slows down the clients as they are busy downloading the streams from all player movements on the screen. Would you be able to work with us and coordinate a way to work this? Here is the starting line to segregate channel data -
https://github.com/pubnub/pubnub-xkcd/blob/master/network.js... see the "xkcd2" at the end. This is the CHANNEL ID. You can take that and change it based on the Region of the world. You can even use the names of the world splices such as
