In organizations where cellphones are banned or restricted, end-user input travels through clusters of Raspberry Pi zero relays – minuscule, single-board, headless computers costing $5/unit – each of which can handle over 16 wired gamepads ($10/gamepad), then re-broadcast the aggregate end-user input wirelessly and in real-time to the secure, authorized IT infrastructure.
Such architecture would add overhead for hardware procurement and IT maintenance but enable us to enter organizations that competitors could not.
