Constructive cricism of the following draft would be useful.  


It's been through a few revisions, but I'd be very happy to revise it further
from operator input.

I would agree that many tricks can be shared between the two protocols, but
that with IPv6 the worm writer is more likely to have to use more tricks
to make their worm more effective.   The point remains rather moot however
while networks are dual stack (except that the state of IPv6 firewalls/IDS
may make IPv6 in some ways an easier target).
