Hi all,
   The following text was added to version -08 of the lw4over6 draft to describe the relationship between MAP-E and lw4over6. 

"Lightweight 4over6 is a solution designed specifically for
complete architecture only. It does not offer direct, meshed IPv4
independence between IPv6 subnet prefix and IPv4 address with or
connectivity between subscribers without packets traversing the
AFTR.  without IPv4 address sharing. This is accomplished by
maintaining If this type of meshed interconnectivity is required,
state for each softwire (per-subscriber state) in the central
lwAFTR [I-D.ietf-softwire-map] provides a suitable solution.  and
a hub-and-spoke forwarding architecture. [I-D.ietf-softwire-map]
also offers these capabilities or, alternatively, allows for a
reduction of the amount of centralized state using rules to
express IPv4/IPv6 address mappings. This introduces an
algorithmic relationship between the IPv6 subnet and IPv4
address. This relationship also allows the option of direct,
meshed connectivity between users."

There was an implicit expectation that similar text (pretty much reversing the order in which the mechanisms are described) would be added to the MAP-E draft as well. In order to do so, we need to do a short consensus check. 

If you believe such text is useful and should be added to the MAP-E draft as well please respond to this mail to say so. On the other hand, if you believe such text is *not useful* and should be instead removed from the lw4over6 draft, please respond and say so as well. This call will conclude on 6th May 2014.

Thanks
Suresh & Yong
