This topic has seen significant interest from the RG side, and in fact
there has been discussion in the RG that this topic might be a candidate
to push into the WG if there were charter interest there.  The RG
decided to make the following draft into a RG document-- it is a problem
statement discussing the problem of traversing legacy NATs and
firewalls:
http://www.ietf.org/internet-drafts/draft-irtf-hiprg-nat-00.txt

An implementation draft was worked on about a year ago, but it has since
expired.  I do not know of any implementation, although I have heard
that InfraHIP is working on it.
https://datatracker.ietf.org/public/idindex.cgi?command=id_detail&id=129
56

The RG is also considering solutions involving HIP-aware firewalls and
NATs, but IMO that type of work (as well as native HIP API) is not ready
for a WG.

A draft that discusses this topic is at:
http://www.ietf.org/internet-drafts/draft-henderson-hip-applications-01.
txt

It has not generated any mailing list or meeting discussion.  I was
thinking of submitting it to RFC Editor as an individual submission.
This topic is not one that necessarily involves interoperability, so I
would like to understand better what is left to do (as a possible WG
item) beyond the present draft.

The integration of SIP and HIP has received a lot of attention in the
RG, but I don't know whether there are any implementations:

iii)
