How does your system handle the massive variance in sensor quality (accelerometer, gyro, WiFi radio) between a high-end iPhone and a budget Android device? Does the 1m accuracy hold up across the board, or does it degrade gracefully? Getting this right seems critical for scaling to a 'billion people'
Interesting experience, as a "software person" coming to LHS while being based at TechHub my experience couldn't be any more different. It's important to note that the experience you've had was with that specific member, and not the hackspace as a whole. My guess is whoever you talked to had a gripe about the influx of members at the time, who came to the hackspace purely for cheap desk space, without engaging with the community or helping around.
