Auto-updating does not require admin right but well, without manifest, the user has the possibility to give or not admin right to his application if needed (if he placed his program in a read-only folder for example), that's not a bad point.
I don't know about Oneclick, but typically, an auto-updating feature is made with a second program that downloads and write the updated program over the old one. the updater is either shipped with the main program, or written by the main program when update is required. If i remember right, it's the way Firefox do
