  Yes -- thank you for that addition!

  Also, in further thinking, I thought of another
  disadvantage for "external" storage. Depending on
  how the links to the external data are represented,
  it may be difficult to relocate the entire "package"
  to another file system (e.g., on another user's
  computer) or even within the same filesystem.

  And it's also worth noting explicitly that the
  mailing list is discussing a hybrid alternative:

  A "zip" file (or other archive) that packs-up the
  textual file as well as all of the external files.

4) It requires some CPU time to decode blobs.
