Auto-Update | Modules Unraveled
Let me start out by stating that I don't know the technical implications of an autocomplete feature. Okay? I don't have the answer. I'm just looking for information. Best case, I can help get something started that will benefit the entire Drupal community in the future.
With that out of the way, I firmly believe that anything is possible with Drupal. And with the "Drupageddon" of late, an auto update feature would be greatly appreciated by many, I'm sure. (I certainly would have benefited from one.)
