Hmm just thinking about HD over the Internet. 20 to 50 GB per movie, or something like that.

At a High Speed Internet service of a relatively speedy 10 Mbps it would take nearly 8 hours to download a 30 GB movie.

If you had a lesser service at 2Mbps, it would take over 38 hours to download.

Of course, they can always use some sort of compression but then it will very likely compromises quality.

Of course home internet services are getting faster so maybe someday but not many are ready for such a service yet.

With great power comes Awesome irresponsibility.
