The QoS-enabled bit will only be across the NBNCo portion, from PoI to your house (and
back again for upstream traffic). You're ISP will have to make a concious effort to
use the capability, so some may ignore it.

On the ISP side of the PoI, that would be up to the ISP whether or not they obey QoS
markings - some of them do, for their own IPTV solution (FetchTV on iiNet for example)
- but generally they do not for general Internet traffic, which is how they would see
an IPTV channel stream from another country.

Sorry, I can't see how these two are linked. You still have ubiquity, its just that a
section of the path understands QoS - and there shouldn't be a cost issue.
Can you explain what you mean by a transient customer, and what the problem you are
concerned about with them?
