Hi Pekka,

The biggest differences between your thinking and HIP seems to be  
that HIP is implemented below TCP, so that it works also for UDP.  I  
think it matches better with the IP semantics, as a single IP  
address is (today) typically associated with a number of co-located  
TCP and UDP end-points.
Then there is also work specific to TCP, e.g Christian Huitema's  
eTCP (or whatever it was called).
I'm glad to see that more people come to the roughly same  
conclusions, independently.  :-)
right, but i think that what is missing in all these proposals is to  
understand the interaction with congestion control, which may be  
critical if they get deployed.
Moreover, understanding how these approaches can help to avoid  
congested paths, could actually be a solution to one of the cuases of  
the routing scalability problem, since many to the TE tricks and  
espcially the updates with more specific that change frequently seem  
to be related with trying to move traffic from one path to a different  
one, probably avoiding congested parts of the network. If there is a  
mechanism that does it automatically for the hosts, then, maybe the  
number of more specific announced and especially the highly volatile  
ones, will substantially decrease. But, i guess there are many  
hypothesis in this sentence, to actually make a strong case at this  
point
