Australia -- interesting test case.

BILLING BY THE BYTE
Internet users in Australia face a new system of charges in January that
could cost them as much as $1.50 (U.S.) for every megabyte of information
they send or receive. Currently, faculty members pay nothing, and
universities pay a fixed annual fee based on the operating grant they
receive from the federal government. Details are still being worked out,
but AARNET says the change is necessary to upgrade the network: "The
increase in capacity is in response to the apparently insatiable demand for
Internet access in Australia..." says AARNET's general manager. (Chronicle
