No you cannot be idolized by EVERY faction in fallout new vegas. At some point you will either be Vilified by the NCR, or the Legion, Or by both. If you side with the NCR then it will eventually start the quest Beware the wrath of Caesar! where it will make you vilified by the Legion if you do not start to side with them. It is the same with the Legion where it will start the quest Dont Tread On The Bear! Finally if you side with Mr. House then it will start both of those quests
