[P2PSIP] Discussion items for the Tuesday teleconference

The paper on the Boeing HIP implementation along with the I-D:
draft-camarillo-hip-bone-00.txt is very helpful to SIP oriented people
like me who are new to HIP. Quite frankly I am close to becoming a
believer, if only some questions could be addressed and where more
details would be helpful:

1. TCP/IP stack use and implementation

If and how can the existing PCP/IP stack in Windows, OSX, Symbian and
LINUX be used or does it have to be rewritten? Is there a workaround and
if yes, can anyone share what it may look like?

Product managers would see the rewriting of the TCP/IP stack to insert
HIP as a major problem to avoid at any cost. Waiting for these OS to
support HIP does not seem a good alternative.

2. NAT traversal

VPN implementations have had problems with NAT and as a result most NAT
vendors have addressed VPN support. What is the experience with HIP
support in NAT, or how much of a problem is NAT traversal for HIP?
Are there any measurements or deployment data that can be shared?

Thanks, Henry

Subject: [P2PSIP] Boeing HIP Implementation of SIP (which is
point-to-pointsecure SIP)

At the Vancouver meeting, there was a joint meeting of the HIP and
P2PSIP groups on Friday morning.  At this meeting, Boeing committed to
sent the P2PSIP group a releasable white paper on the Boeing HIP
implementation that is, in effect, point-to-point secure SIP.  

 <<NGI_SMA_Boeing_VoWLAN_Demo_White_Paper_12-8-07.doc>> 
The next step beyond this is to hold a teleconference in the first or
second week of the new year to discuss this paper.  Please note that
although the identity in this example is an IPv6 address, any
cryptographic identity can be used as a name in the HIP namespace.  The
Boeing intent is to use PKI crytographic identities in the HIP
namespace.
