It's funny you should mention that. When it was pronounced a few weeks ago
that AURSC had support from a silent majority, I must admit I was a little
surprised. I wrote a program that collected the authoritative nameservers
for the domains of all the IAPs listed in the ISP List. It then queried
all these nameservers as to their knowledge of "legacy" domains,
and "AURSC" domains.

Obviously this isn't perfect but for a large percentage of providers,
it is very likely the DNS their clients use as a resolver is going to be
one of their authoritative nameservers. So the results were just to get a 
ballpark idea.

Anyway, I never got around to running it, but your post reminded me. So
here are the results..

Providers that returned records for "www.ah.net", but not "www.au.rsc": 591
Providers that returned records for "www.au.rsc":                         4
Providers that returned records for the domain they are authoritative
 for, but not for "www.ah.net", "www.au.rsc" (presumably don't forward): 13
Providers whom I got no response from (timed out, etc.):                 17

FTR, here are the nameservers that knew www.au.rsc:
  central.cth.com.au (1) [Closer To Home Systems: Nambour-QLD, Caboolture-QLD]
  nhj.nlc.net.au (1) [NLC: Terrey_Hills/Sydney-NSW]
  saturn.thepla.net (1) [CyberGate PlaNet: Sydney-NSW]
  gecko.znet.net.au (1) [Zed.Net: Silkwood-QLD, Innisfail-QLD]

Draw whatever conclusions you will, but personally I find it hard to 
believe there is anything but a trivial amount of use of AURSC in relation
to the number of people using the Internet in Australia.
