David, I fully agree with you. HIP has not been widely deployed and NAT
traversal, mobility and multihome are still developing. All in all, HIP is
not mature enough to provide stable service for upper applications. 

On the other hand, the requirements from HIP-BONE as pointed out by Gonzalo
should be considered while designing peer protocol. Fortunately, it is not
hard to be met. Most of the existing proposals have taken modular approach. 

Regards!
