HK is too isolated from the mainland to cause a chain reaction there. So the only way to get China to allow them to have democracy is to make the cost of a crackdown greater than the cost of retreating for the communist party's calculations. I would say the outside influences would want to keep it purely peaceful for as long as possible. Any big violence would give the chinese the opportunity to crush them under a plausible reason. Let it build up until the HK government is forced to incrementally support the HK people.
