reviewing drafts for tomorrow strikes me that several touch on the 
general issue of how a host should determine whether to use IPv4 versus 
IPv6 when both are available.  I might suggest juggling the agenda a 
little, grouping them and having a short general discussion on which if 
any of these are appropriate to adopt as WG items, or perhaps combining 
some drafts?  Plus or minus I miss the point on any of these drafts...

sorry for the late suggestion, but better than saving it for 9:00am.  
Regardless, we should consider the interaction or synergy of these 
proposals.
