Not that Wikipedia would be free from error, but they explicitly state 
that having a different key for each /individual/ player is the major 
difference in key management between CSS (as used on DVD, having one key 
per player model) and AACS (having one key per individual player) - the 
idea apparently being that keys /can/ be revoked without hurting many 
honest consumers.
