Any updates? :D
The ExitGames/Photon team appears to have concluded that there's not enough interest in their JavaScript SDK and in my use of it in a C2 plugin, so are focussing their efforts in more profitable directions.
Taurian (the OP) also appears to be pursuing other interests.
No-one here seems to have developed my C2 demo in any direction.
So (with some reluctance), I'm turning my development efforts to other projects that have been gathering dust on my workbench.
I'll pass the multiplayer/Photon baton to jayderyu and awarmenhoven, who've got a very promising project underway. Good luck, guys!
