Hi,

It's not web-driven app, there are push notifications, in app purchase, google 
api authorization and a few more. WebRTC allows me to use some "call center" 
infrastructure with TURN and STUN servers provided by VoIP provider. They have 
commercial JS library where all webRTC communications is done. I can access 
camera no problem, did that for QR codes, but then I would have to do all 
webRTC related stuff myself.

Best Regards
