Leaning on the Google WebRTC stack for the software that runs on the Pluot hardware device has been fun and interesting. We wrap Chromium (via Electron nee Atom Shell) with a UI designed to take full advantage of the HD TV (or two TV's) pixels and a provide one-click meeting start via any browser that has been paired with the room as a remote control using code displayed on the TV.
The web client uses largely the same code as the hardware device to perform its call machinery and screen shares.
We'll try to write more about this in the days to come, this week we're turning screwdrivers in the garage to ship orders, and updating the web layouts to be consistent with the in-room experience.
