Didn't have Wi-Fi so had to do it fully locally on my laptop.
1. Set up Android simulator with Google Play services. Log in as real Google account. Install Warpcast and log in as comm.eth
2. Run `landing` with `yarn prod` and `keyserver` with `yarn prod-build`, but with `keyserver/src/keyserver.js` patched to all connections from anywhere (not just `localhost`). This step is necessary because `landing` (like `web`) assumes a local address of `localhost` and as such can't be loaded from an Android emulator (which sees it as 10.0.2.2)
3. See video. Note that registration is not possible with this setup because keyserver auth is broken since it tries to talk to prod identity instead of staging identity.
