Questions that need to be asked of the network: yes. Note that it's not
enough to trust the other party; I have to trust that all parties who
are providing information that might impact my answer. That's why I
don't think this sort of trust ever really exists.

Questions for which the answers can be measured independently (e.g.,
pathchar): no.
