Patient chat: Local Peer-to-Peer Video Chat for Biosecurity Medical Contexts

Phone-to-phone video chat without Internet or a Local Area Network needed.

A single-purpose application allowing high-quality audio and video chat between two nearby mobile devices without external networking. Essentially turning two phones into a pair of video-enabled "walkie-talkies", connected to one another by Wi-Fi signals without any other network or devices involved.

Intended for use where biosecurity makes direct contact difficult and unsafe, allowing easier communication with patients inside biosecurity zones.

Primary use-case (based on requests from medics) is a COVID-19 medic checking in frequently with a patient in an isolation room without physically visiting each time.

Medics can use it to interact more frequently with their patients while conserving PPE and minimizing exposure risk. Families can use it to interact with loved ones that cannot be safely visited in person. Works like a baby monitor, but deployed on any mobile device without additional hardware.

Open source and freely available to all users. Copyleft in hopes that improvements made by commercial contributors will be shared.

Spec reasonably advanced, and github repo stubbed out.
