Whatever the possibilities offered by satellites, they only solve part of the problem of the World Wide Wait. This very page, for example, is slow to cross the Pacific, a situation made worse by the fact that I spend the first five minutes waiting for the ads to arrive before the text happens.
Companies using ISPs to host their pages face the worst of the under-spec problem.
An ISP putting a hundred corporate pages on one Pentium box is pretty much ripping off its customers, who may never know that download times are in minutes, not seconds. And finally - satellite transmission may offer a wider pipe, but not a shorter pipe.
