[TICTOC] IPsec security for packet based synchronization

[Danny Mayer <[e-mail]>]

The minutes of the taipei meeting state this:

If the answer to question 1 is yes for 3GPP Femtocell then there needs
to be an explicit answer to why and what this is with a reference to
supporting documents and the section of the documents.

Also Yang disagreed about the vunerability of identified timing packets
so he should state exactly why he disagrees along with any supporting
documents and sections of those documents.
