*scratches chin*.

When I was a boy :)  We used to drive HDs of video across Java on motor
scooters for the same reason - bandwidth. Engagemedia even built a system
of localised pods and "sneaker nets" so the videos could be "browsed
online" when actually just being cached on locally installed servers.

While I'd take flying to Japan every day now, riding across Indonesia was
out little indy version of that treat.

I wonder if it will ever stop being effective on that top edge of data
size/distance. Happy to put my hand up for a trip out to Mars to pick up
their big data if anyone is looking.

"The fact that you're still saying something like 'feminism gone mad'
suggests that feminism hasn't gone mad ENOUGH yet."
