Re: [v4v6interim] [BEHAVE] [46translation] Proposal for new BEHAVE charter

[Magnus Westerlund <[e-mail]>]

Anyway,

Are anyone that thinks that NAT66 is so important that it takes
precedence over the NAT46 translator work? If not, can we postpone this
until we are ready to publish something on address family translators?

The reason I ask the above is that we will have enough work for all the
people in the translator work. Thus trying to avoid splitting the forces
to thinly.
