tech-userlevel@netbsd.org, which is where I saw this.)

  Have you looked at mount_umap(8)?  I (naively) think it would
solve most of your concerns.

``The mount_umap command is used to mount a sub-tree of an existing file
  system that uses a different set of uids and gids than the local system.
  Such a file system could be mounted from a remote site via NFS or it
  could be a file system on removable media brought from some foreign loca-
  tion that uses a different password file.''
