** Maven-Artifact

  This is wholly dependent on Maven-Wagon, above.

  We could possibly use a flag on a particular Wagon to see whether it supports
  offline mode, and then test to see if the file-based basedir for an artifact
  repository works...if it doesn't work, we can mark that repository offline...

  OTOH, all offline-mode checks can probably be run from Wagon-based APIs.
