For what it's worth, I think P2PSIP over HIP is a fantastic idea, with
the caveat that HIP should be deployable within standalone applications
by statically linking some BSD-licensed library (ie, without requiring
users to make TCP stack changes or install virtual network interfaces).
Basically, my vision of HIP is like a standardized version of Amicima,
such as was just integrated into Flash by Adobe.
A VPN/virtual-interface over HIP would be really cool -- don't get me
wrong. It'd be like an open-source, standardized version of Hamachi.
But as an application developer, I wouldn't ever ask my users to deploy
some scary virtual tunnel just to use my thing.
Personally, I don't see any good reason not to use HIP. It seems like
such an obvious duplication of effort I don't understand why the IETF
allows it. Though admittedly I haven't followed it closely in the past
few years.

Hi Dean,
for sure you know about the Not Invented Here syndrome IETF WGs usually
develop, right? ;o)

Hi Henry,
Yes, I know, developing HIP code looks like opening a whole new can of
worms, but nothing compares to what we are looking at now when
trying to
traverse NAT, support mobility, multihoming, etc. for each application
protocol and their various flavors separately.
yes, that is what HIP is about (i.e., implementing those functions at
a lower layer so that they do not have to be redesigned by every
single application-layer protocol).
This asks the question "Why don't we believe in HIP in this role?"
Is it because we've seen HIP struggling to advance for many years and
think we can move more quickly?
Is it because we think the IETF's immune system will suppress HIP but
that application-level work can move through?
Is it because we think that doing this stuff at the HIP level requires
widespread OS and IP stack changes, but that we can deploy
application-level solutions without it?
Is it because we think that if HIP solves the problems, then there
will be no fun work left to do on applications?
Or is there something else?
There must be some reason, as I would think that if people really
believed in HIP that the entire resources of the IETF would be bent
towards getting it wrapped up and ready to go, since solving these
problems again and again for every different application makes no more
sense than would reinventing IP for every application.
