There is a load of v6 traffic in most v4-only networks I work on, it's
just common for it to be dismissed by network people as "background
noise".

this is likely due to those networks having clients in one of two configurations...

1. default OS settings which have IPv6 turned on even when it is not necessary 
(windows is bad for this and known to have this setting one by default)

"Not necessary" is the wrong thing here.  IPv6 is going to be necessary, and if you listen to the "omg the world is 
coming to an end we are running out of IPv4 addresses OMG !!!!eleven!1" people, we're going to need them soon.

Many OSes come with IPv6 on by default.  I know Fedora, Windows, and OSX do.  It's probably time we stop shutting it 
down, and figure out how to secure it instead of trying to prevent change.
