[x3d-public] Suggestions for multiuser controls?

[John Carlson]

I have enabled controls on iOS for one of my webapps.   I used an extension
of JQueryui to enable sliders from X3DOM examples (see custom shaders
online).   It would be good to provide examples for iOS and other touch
devices in X3DOM.

I believe that I will now try to achieve multiuser touch controls in
JavaScript.  Suggestions are welcome!  My old friend is socket.io, but I’d
prefer serverless.

Thanks,

John
