Part of the 'culture' of Star Trek was that at any given time, with the appropriate means, anyone could control anything, from anywhere. It didn't matter how critical the system was.
The Enterprise-D and other starships were often (partially) controlled by enemies or other entities who weren't even phisically inside the ships =)
That being said, DS9 rox!

When I installed GNU Hurd on my system in 2005ish, I was surprised to find out you could run guile or other commands without even logging in (but as a not-logged-in-user you couldn't really affect many things). Apparently this was somewhat inspired by the RMS-of-the-80s philosophy of "why lock people out?" Is this kind of like that?
