It assumes global visibility, and unspoofability: Every node must know the entire network, and it must not be possible for a node to lie about its peers. The latter is something we need to address for premix routing. As for the former, we will need *local* visibility for premix routing - we need to be able to see every node in a few hops, and determine with a reasonable confidence whether their existence is plausible - but global visibility would be expensive, and would help attackers.
