Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,

    Do not update this, Doxia will be decoupled completely from 3.x and someone can
    create a rendering engine for it if they like when the release stabilizes. JVZ
