Khamenei's rival speaks out?

Iranian politics are not my strong suit, but one thing leaping out at me from Andrew Sullivan's coverage of the post-election unrest is this statement by Grand Ayatollah Montazeri, which reads in part (not correcting the evidently clumsy translation):

1- A legitimate state must respect all points of view. It may not oppress all critical views. I fear that this lead to the lost of people’s faith in Islam.

2- Given the current circumstances, I expect the government to take all measures to restore people’s confidence. Otherwise, as I have already said, a government not respecting people’s vote has no religious or political legitimacy.

3- I invite everyone, specially the youth, to continue reclaiming their dues in calm, and not let those who want to associate this movement with chaos succeed.

4- I ask the police and army personals not to “sell their religion”, and beware that receiving orders will not excuse them before god. Recognize the protesting youth as your children. Today censor and cutting telecommunication lines can not hide the truth.

No, tell us what you really think, sir!

Montazeri was Khomeini's original pick for his successor, but after Montazeri spoke out against various regime abuses, the death of Khomeini was followed by the sudden promotion to ayatollah, and enthronement as Supreme Leader, of Ali Khamenei, who continues today in that post.

For Montazeri -- still considered the #1 spiritual authority by many Iranians -- to speak out like this, after having spent much of the past decade under house arrest, must surely be important.

... FWIW, compare this from Robert Baer:

... Khamenei's legitimacy has been in question from the day he succeeded Ayatollah Khomeini in 1989. It was widely understood among intelligence analysts that Khamenei did not have the religious credentials to succeed Khomeini as supreme leader, Iran's head of state who is supposed to be the most learned religious cleric. In fact, Khamenei is not even really an ayatollah--his license was in effect bought--and he has no popular religious following as other legitimate ayatollahs do. * * *

A sure signal of Khamenei's political weakness occurred when Ahmadinejad attacked former president Rafsanjani for corruption during the election campaign. Rafsanjani is and always has been a threat to Khamenei's legitimacy. Not only is he more of a real ayatollah, but he is also Chairman of the Assembly of Experts and the Expediency Council, two powerful government bodies. The Assembly of Experts has the power to remove Khamenei and appoint a new Supreme Leader. And though facts are impossible to come by, it is almost certain that Ahmadinejad's attack on Rafsanjani could not have been made without a green light from Khamenei, who knew that charges of Rafsanjani's corruption would strike a chord with Iranians. Khamenei saw and probably still sees Rafsanjani as a threat to his power, even to his position as supreme leader, and this was an effective way to pounce.

Still, if the protests and demonstrations in Tehran cannot be controlled, we should seriously start to wonder about Khamenei's future. Rafsanjani is rumored to be in the holy city of Qum plotting against Khamenei, seeing if he has enough votes in the 86-member Assembly of Experts to remove Khamenei. A vote recount is unlikely to change the results of the election, but it could lead to more demonstrations, which backed by Rafsanjani and the other mullahs, might just end Khamenei's 20 year run.

Ya think Rafsanjani and Montazeri have been chatting in Qom?
