Hi,

high-level changes are as follows:

* The new draft version follows the ice-bis version, so I removed aggressive nomination * Clarifications in the subsections in section 4.12. Relaying Considerations
  * Fixed some nits

Open questions:

  * What should do with compatibility with RFC 6078 (HICCUPS)
* Connectivity tests should be skipped unless ESP_TRANSFORM is negotiated?
  * Steps 5-6 could be skipped in the handoff sequence? See fig. 6.
  * 4.12.3.  Handling Conflicting SPI Values
    * Should the Responder send a notify on SPI collision?
* Removed text about registering with multiple addresses because I think this does not work with HIP (or at least, requires multihoming) * Lower the connectivity test pacing value from 20 ms to 2 ms (as in the ice-bis specs) in section 4.4?

Abstract:
    This document specifies a new Network Address Translator (NAT)
    traversal mode for the Host Identity Protocol (HIP).  The new mode is
    based on the Interactive Connectivity Establishment (ICE) methodology
    and UDP encapsulation of data and signaling traffic.  The main
    difference from the previously specified modes is the use of HIP
    messages for all NAT traversal procedures.
