It appears that this movement-kind-of-thing is being sustained by some (tacit) support from the old guards of the 1979 revolution. So it is more of a conflict within the stake-holders of the Islamic regime than something aimed at overthrowing the supreme-leader-dominated undemocratic power structure set up by the Islamic revolution. Ahmadinejad as a newcomer seems to be trying to have more hold on all state matters including those traditionally controlled by the clerics in committees like the guardian council. So, there clearly is an internal fight for power. I can't support Ahmadinejad's rhetoric on Jews, Israel and America but I don't think his election was a toal fraud.

Though Change in Iran is long overdue, the size of these protests hardly indicates the possibility of any appreciable change any time soon. Even a re-elecion and a victory for Mousavi (which does not seem likely) would hardly mean anything as far as Change is concerned. Western media's coverage of protests with women's participation and their implications seems to be exaggerated  in essence. Only those living in Iran can tell the truth. It will definitely take much more time for any movement to take momentum even if it succeeds to sustain.
