Because we may be the only chance for life on earth to spread to other planets, ... ever.

If we botch it this time, life may not have enough time to evolve another space faring civilisation. Think about it. Though doing nothing we may seal the fate for all of life.

We are part of a much larger ecosystem, without which we cannot survive. If we travel to the stars, so does life - which will continue to evolve.

If there is some great project humanity should try to tackle, it would be this.

Nihilism and Absurdism. At least I can't find any meaning or value in PHP. Kierkegaard and Nietzsche would probably agree.

If you are going to be deterred from coming to the US over the requirement that you register online and cough up some fingerprints I suppose you really didn't care that much about coming in the first place anyway, did you?

Afaik, no state on this planet has my fingerprints yet, and I do not plan on handing them over any time soon. If that means not to travel to foreign countries where I would love to go to, so be it. I'll watch documentaries instead.

I have my principles, and a change of law will not change them!

Yes he may. Though if he uses of-the-shelf VPN routers the number of ipsec tunnels may be limited (via license or something else) and if he has only 10 shops he would already need 24 tunnels, which have to be configured at either end. So that makes 48 configuration entries. A lot of work and a lot to maintain.

You said it. He would gain nothing from using BitTorrent over - say - a HTTP download if he has to route the traffic of all(!) his shops through his main shop.

Because all his shops must then be connected to every other shop. This are many ipsec links to maintain. It's easier to just use the internet and encrypt your data.
