That's the problem, though.  If the vendor doesn't support or test it, I 
can't rely on it in production.  That's a big part of what I mean by 
lamenting embedded systems designers.  Until we have IPv6 parity, all 
those printers and multifunction devices sit on their own IPv4-only 
VLAN, accessible only through print servers so that I don't have to 
worry about things like unsecured SNMP over IPv6 because the vendor 
didn't bother making their ACLs dual-stack or only added the "read-only" 
config bit for IPv4, leaving the IPv6 SNMP open to unauthorized writing 
(actual observed behaviour with a major printer manufacturer).
