Well, maybe.  Personally, I think the threat of listwashing is overstated.
The really slimy senders have lists so dirty that no amount of washing will 
clean them.

But anyway, I'm seeing a lot of assertions about how IPv6 mail will work,
and precious little running core or simulations.  As always, anyone want
to do some, you know, research?
