Looks useful, although it's not something I think I'd signup to wait for. This strikes me as the kind of thing I'd stumble on when writing a game and thinking "jesus this has probably been solved before, let me just google this real quick.." On the other hand, this is the sort of thing that's also pretty easy to implement on your own. So: your main competition is probably internal teams that think "why would we give control of this to someone else?". So I would design accordingly. As an aside, I would totally try to integrate this with existing dev communities. I bet you'd have a lot of luck if you were to make a Unity plugin/script, for instance, or maybe a UE4 thing (not sure the multiplayer story with UE4, but I know with unity it kinda sucks). All the same, I think this comes down to your goals. If this is like "a project to make some money on the side", I think it's a great idea, on the other hand, if it's a startup idea I just don't think there's really enough of a market there.
