Improve how fluid connections are made

[Pjaerr]

First thought was to use QR codes but IOS doesn't support a reader directly within the web app so my second thought is to automatically connect two devices if they are on the same network (check IP: https://github.com/websockets/ws#how-to-get-the-ip-address-of-the-client) but this could cause issues on semi-public networks such as within a student accomodation so probably not doable.

Any ideas welcome.

Could show a long GUID on screen (currently only show the first 9 characters) and then provide the phone with OCR ability if that exists (https://github.com/naptha/tesseract.js#tesseractjs) -- Probably too slow for actual use but just an idea.
