"That was my thought exactly - why is NBNco trialling a technology that it won't be able to deliver to the significant majority of connected customers, delivering speed that they believe nobody wants?"
I always wondered why they don't push hard into the corporate market and I expect they want a piece of the pie, considering just our 100Mbps connection over dark fibre is close to AUD $1,000 per month (including data downloaded up to a certain amount), a 1Gbps connection at half that price would get snapped up by quite a few large and small businesses I expect.
