It's my opinion that while it may not happen the first 5-10 years, any 
home will consist of multiple routers.

Any architecture we develop should in the long run handle multiple 
upstream providers (implying multiple provider CPEs) and multiple 
hierarchies of routers in the home. I also believe we need a routing 
protocol, plus a mechanism to do source based routing out to the correct 
ISP. Some of the needed mechanism might need to be developed in other WGs, 
but this WG can determine the need.

This was discussed in quite a lot of detail on v6ops a few months back for 
the CPE router requirement draft, I'm sure there are discussions in other 
WGs touching on these topics as well.
