I don’t think this will go anywhere. This is not like Egypt where the army was facing people they knew. Iran is pretty big. There is a lot of class division in addition to the geographical divides. The gov’t can bring in units from other places (just like the Chinese did at Tienanmen way back when) and face what is mostly the tech savvy well off youth who have some idea what its like in the west. They’re the ones that are being hurt by the gov’ts policy of isolation. Until this group can get their protesting demographics to spread the Iranian gov’t can just squash them as soon as they get out in the street.
