From what I've gathered they are currently on one weird set up, they are using the new v2 url for getting the actual token, but as it lacks formatting they seem to be using the handshaker via another url
http://www.abc.net.au/iView/Services/iViewHandshaker for display puposes (such as the bandwidth checker) rather than trying to parse the v2 string. I could be wrong but that's what I got from a url snoop
