* Implications for Resolution

** Dependency Resolution

  This one is obvious...we only have access to the repositories using
  the file:// protocol and living on a truly local filesystem when
  offline.

** Plugin Resolution

  This is similar to dependency resolution. Plugin repositories not
  using file:// or not residing on a local (not shared) filesystem will
  be unavailable.
