   	Yes exactly - X11 was designed with a politer more considerate set   
   of network users in mind (inside universities) - people who might play a   
   prank (run Xroach on all X displays in the lab or play strange noises   
   quietly through network audio[1]) but would never intend harm and would   
   (mostly) carefully avoid looking at private information or at least not do   
   anything with it but giggle.   
      
   	It was a different world, the internet has spread to far less   
   pleasant people since then.   
      
   [1] I've seen both of these in places of work[2], to be fair the first did   
   cause a scream! So perhaps not totally harmless pranks.   
      
   [2] We didn't have X terminals at college (circa 1980), but someone at   
   Cambridge made the Enterprise fly round a room full of 80x25 terminals most   
   of which were in use at the time. Phoenix was easy to hack - so nobody   
   bothered except to do something fun and that was rare.
