REAL-TIME STATUS
In the room? Passed out? Gone feral in the dealers' den? Set it from your phone and the door handles the rest.

Stick an e-ink screen on your hotel door. Update your status from your phone. Never answer 'where are you' again.
In the room? Passed out? Gone feral in the dealers' den? Set it from your phone and the door handles the rest.
A little e-ink screen that sits on your door and never dies. Shows who's around, what they're doing, and a QR code so people can find you.
Randos get the basics. Friends with the passcode get the full picture. You pick who sees what.
