As I briefly mentioned today, there has been some complementary work in
the HIP RG that discusses the handling of non-routable identifiers in
legacy applications:
http://www.ietf.org/internet-drafts/draft-henderson-hip-applications-02.
txt, 
the main differences being the use of KHI (now ORCHIDs) in HIP instead
of CGAs.  

Until recently, the HIP drafts defined a "Type 2" HIT with the property
that the upper 64 bits contained support for two levels of hierarchical
naming (enabling reverse resolution), with the lower bits being drawn
from a hash of the public key, but this HIT type was dropped due to lack
of interest last year:
http://www1.ietf.org/mail-archive/web/hipsec/current/msg01519.html
It was also felt by some that 64 bits of hash was insufficient to
protect the binding between HIT and public key.
