Thought the demonstration of BT was interesting (at ~5:00): "...and you're downloading the movie right now?" "that's right" "the bits moving away...are pieces we have and are sharing with someone else." So CBS was participating in the very activity their program was out to show is illegal...interesting.

Why was this voted down? Do people not ever just coast? What if you're approaching a stop light that's red, for example? If you're not too close to it, it makes sense to let off of the accelerator early in the hopes that it turns green before you have to use the brakes.

Well, if their internet connection no longer exists...

Sounds to me like the parent is speaking of multiple partitions on the same disk. While this is theoretically fine, when I'm doing things like upgrading my OS and wiping a partition, having all of my data so close makes me nervous. I have them on separate partitions on separate disks and it makes me feel better.

UDP would actually better here, since UDP packets are send-and-forget, though you're not guaranteed delivery. Over a high-latency network, you don't want to bother re-transmitting anything for voice communications, because like the above poster said you'd have seconds of silence waiting for the retransmissions.
