I’ve seen requests for a pure web player (no installation required) here, but don’t think I’ve seen a direct comment about the roadmap for this.
As far as I can tell, poking at things, you’re using Unity under the hood? I understand that the WebGL target of Unity3d is … limited compared to other platforms, but given that you’re only using a limited area of the API: Do you think this might be a viable target after high priority ones (desktop operating systems, mobile platforms)?
In case I’m wrong about Unity3d or in case the WebGL target doesn’t work for you, would WebRTC¹ potentially in combination with Encrypted Media Extensions API² be something worth investigating?
