Re: I-D Action: draft-ietf-hip-native-nat-traversal-14.txt

Hi,

I read the latest version of the ICE specs. Based on this, I included 
more details on ICE processing to the HIP NAT traversal draft. A quick 
summary of the changes:

* Introduced more details from ice-bis draft
   * New terminology
   * Aligned connectivity check procedure to match with ICE (3-way check 
is now 4-way)
   * Ta minimum value is now 5 ms (according to ICE bis)
   * 4.9 Handoff: first update HIP relay to in order learn new server 
reflexive locators
   * New sections:
      * 4.6.3.  Rules for Concluding Connectivity Checks
      * 6.6.  Amplification attacks (new section)
      * 6.7.  Attacks against Connectivity Checks and Candidate Gathering
      * Appendix C.  Differences to ICE
      * Appendix D.  Differences to Base Exchange and UPDATE procedures
   * 7. IANA Considerations: added UNSAF considerations (references ICE)
* updated references (some drafts are now RFCs)

Feedback is welcome! For people already familiar with HIP, I'd recommend 
reading "the diff to normal HIP" in section 
https://tools.ietf.org/html/draft-ietf-hip-native-nat-traversal-14#appendix-D
