I would be really delighted if Nechung turned out to be a Buddha, however, I got the impression that the Dalai Lama, though he relies on Nechung, considers Nechung a spirit. (I am looking for a reference). I have never quite worked out why it's supposed to be okay for him to rely on a spirit, but by just misnaming Dorje Shugden a 'spirit' he is able to cause biogotry and prejudice against so many Buddhists.
It is strange too, that the Dalai Lama always says he wants to emulate the 5th Dalai Lama--- not all the Dalai Lama recognitions have been enlightnened so, he picked the 5th to emulate, which would indicate to me, along with his illogical arguement for Nechung and against Shugden, that maybe he just wants for people to ignore anything he says with his mouth. Maybe his activity this life is very political, and will get so bizarre, that we should just ignore him. If he is an enlightened being, I think what he is saying is "ignore anything my mouth says, because I am not in a position to give good Buddhist advice."
