With MHAP this would not be needed as the PI would enter the Host Node
with the identifier in the header and could be used for the checksum, in
that architecture view.  

The use of the HOA with a MIPv6 architecture would also avoid this
problem.

Looking at GFN and HIP currently.

This is more complex.
