Give me a link to the labeling section and I'll let you know if I've seen
it in the wild. I'm out in the field now (got sick of the desk) and see a
lot of commercial/retail plants.
I doubt that it's going on in retail, except maybe Lowe's Hardware. They
do love MM fiber and just did a nation-wide network upgrade to gigabit
everywhere in the stores. But then again, the label specs were kinda hit
and miss.
Sadly I've seen no IPv6 in any retail shops.
