Have a look at Wimax (particularly ASN gateways) for an example of a  
wholesale Layer3 environment.

For the VLAN architecture have a look at TR-101 from the dsl forum: http://www.broadband-forum.org/technical/download/TR-101.pdf

It may be that the NBN needs to be L3 just to cut down on the  
components required. A wholesale LAC/BNG/BRAS arrangement is going to  
cost a bundle to support millions of Australians at 100M speeds, only  
to be replicated at every ISP for the retail interface!
