Gonzalo,
Below are my WGLC comments on this set of drafts.  I will send some detailed comments on each draft in subsequent messages.

Overall, my opinion is that this set of drafts is not yet ready to publish, because there are some missing elements in each draft (see the detailed comments) and also because I think the overall clarity of the specifications could be improved.  In particular, I found several instances where I had a question of how something worked in one draft, and later found the answer somewhere else in another draft.  These types of things could be probably addressed by some reorganization.

Also, I did not have a clear big picture of this type of overlay until I read all of the details of all drafts.  Some type of "Protocol overview" section in the framework draft, with particular attention to interface definitions or modular decomposition, would help.  For example, when I read the RELOAD draft, I found a nice overview section including architectural diagrams in Section 1 of the draft.  Maybe Section 7 of the hip-bone draft could be moved forward to Section 1 and expanded.

I would suggest:

1) merge draft-ietf-hip-bone, draft-ietf-hip-via, and draft-ietf-hip-hiccups into one draft.  Keep the reload instance as a separate draft.  Keep the certificate draft as a separate draft.

2) write a protocol (or framework) overview section in the draft-ietf-hip-bone-04 and place it in Section 1, like was done for RELOAD.

Note that I did not review these drafts from the perspective of whether all of the new crypto defined is correct and consistent with the rest of HIP.

Regards,
Tom
