There are no ownertrust paths but the pathfinder shows me how
many disjunct paths are possible from my key to the other key.

An attacker would have to introduce fake signatures in every of
the disjunct paths.

Since I choose the first nodes on the path because I checked
their identity (papers) and signed their key, I have some means
of making the attack more difficult.

(All this implies that the pathfinder does not lie to me.)

Ciao; Gregor
