[Roger Clarke]

A mate of mine lives beside a loch 50km north of Glasgow.

Having been, among many other things, Douglas Adams' IT Director, he tends to install gadgets.

He installed a Skybell ("Answer your door with a smartphone"):

Compare your (someday) NBN with the southern foothills of the Highlands:

" ... thanks to the abysmal communications infrastructure of the rural UK, we're on a satellite connection, so a ring on our doorbell is relayed through our home network, then 72,000km+ to the Skybell servers which, if they deign to respond (which they don't always do), then send the signal back another 72,000km+ to our network, which then alerts the Apps on our phones and tablets. Or not. If I then choose to activate the video feed to see who's at the door, the process is repeated, this time at video bandwidth".
