Last month I put together a wiki page to track and describe the changes that will be proposed for IPv4 rework:
http://www.nsnam.org/wiki/index.php/IPv4_cleanup

There is a repository to track this work  (http://code.nsnam.org/tomh/ns-3-ip).  Presently it implements items 1 and 2 listed on the wiki page.

More recently I've been working on the possible API and design for routing rework.  After some discussion with Mathieu, I have written up a sketch of how I envision the design in a file called "README.routing.txt" in the top level of that repo.

Here is a link to the overall design approach:
http://code.nsnam.org/tomh/ns-3-ip/raw-file/0c9f7a1e050a/README.routing.txt

There is also a file "README.routing.api" with more details about the API:
http://code.nsnam.org/tomh/ns-3-ip/raw-file/0c9f7a1e050a/README.routing.api

I plan to work on implementing this fairly aggressively through the rest of the week (trying to meet Craig's merge deadline) so please send comments if you care to review it in the meantime.  I also will try to coordinate with Sebastien along the way.
