Comment (by nejucomo):

 I'm about to embark on an international flight, and the state of my
 internet access tomorrow will be unknown.  Therefore, if anyone wants to
 increase the chance of MDMF successfully landing in the 1.9 release, feel
 free to review this ticket in parallel!

 Here is what I'd like to accomplish on the flight:

 Learn the format and cryptographic derivations of the MDMF cap.  There is
 a good deal of discussion in these comments about the share serialization,
 but not the MDMF cap.  I'll first check for documentation in the
 repository or the wiki for this, otherwise I'll revert to code.

 Think carefully about the share file format.  I have only skimmed over the
 proposed layout without reviewing which fields are authenticated and how,
 as well as what the authentication tells the reader of a share file.

 Brainstorm how I would implement the protocol, given what I know about the
 MDMF cap and the share file format.  Jot down some notes.  I'll use this
 as a reference point in the code review to notice divergences between my
 brain-stormed implementation and the real one.

 Read the actual code, noticing any confusing bits.


 After I land, I'll attempt to get internet access to dump my feedback,
 especially an approval for release or please-fix-X comment.
