I will read the paper, even if I think we are dealing here with true 
liars. I mdestely think that the problem is that the computatino of LQ is
based upon two parties, the sender and the neighbor. I think that upper 
layers protocols could cooperate in order to vote the correct value of LQ.
But I don't know. I just wake up right now....
