I like this line of thinking, though is it really "simple" compared a key? :p
> Physical keys to the space should be distributed very judiciously! Note: If a key-holder loses their key, they must personally pay for replacing the lock and all keys possessed by other persons, otherwise over time there will be no security because there will be keys in random hands.
I think this goes a little too far, IMHO, considering just how easy it
is to pick the lock.
