Scratch

i know about mesh but it is quite complicated.
maybe there could be online servers people could create and you can connect to for example

my first project fight
____
description server:223

-------------------------------
so bob (maker of project) set up server 223 offline and all the imformation go is into the server and anyone who plays it is automatically connected
when they press stop or quit out of the downloaded project they are disconnected.
i think it is possible to create a server (pretty sure my dad set one up)
yours sincerly
