One of the issues with the move to the cloud with formerly desktop software is exactly this. I used to use the analogy of an army using guns, except instead of a magazine holding bullets they had a long hose feeding them rounds. It sounded great to the generals, because instead of carrying around 20lbs of munitions, the soldiers just needed to carry around their guns. Of course all it took is for somebody to put a kink in the hose to put them out of the fight completely.
