I love stuff like this... and how people solve problems.
What do you do if you have a locked gate but more than one person is permitted to open it? You don’t want lots of different key, because if one person loses their key --- everyone needs a new one.
The solution?
Multiple locks, chained into one long lock. Open any lock to open the gate. This way each person needs to manage their key (and lock). Genius.
Goes to show that there is always a solution. Always a better way. And simple, once again is better.
Found this on the Improvised Technology portion of Kevin Kelly's site.
