[I've been away from this site for a while, so apologies if I get the terminology wrong; feel free to correct/educate me]
The Indiegogo page make it sound like the locks support master keying. With the re-configurable key, it seems to me like you could figure out the master key configuration one wheel at a time from a non-master key. Although the example they show, it might be as simple as "shared" locks only using two wheels, instead of four.
I might have to buy one just to play with it
