The weighted coin scheme is bad, but at least the attacks are probabilistic 
- the nearest location attack is not. If you get two linkable requests from 
the same peer, both with nearestLoc==prevLoc, one with a target more than 
0.25 clockwise from the peer and the other more than 0.25 anticlockwise, 
the peer *must* be the originator.
