Hi all,

I went through the requirements draft and the strawman proposal. 
Initially, I did not plan to comment because I just wasn't quite sure 
whether I misunderstood the entire proposal completely.

When I first read the document then I got the impression that all this 
stuff already exists. I thought that you are replicating the 3GPP IMS 
work (without referencing it). The only difference I saw was that backup 
paths were established but I wasn't quite sure whether this is a good 
idea anyway.

So, what is the new idea about combining SIP (name-based routing) with 
path-coupled signaling?

Ciao
Hannes

PS: I haven't read the recent HIP proposal
