Nasty things happen when networks become saturated. Maybe the killer app for the Internet will be a rapidly deployable underlying carrier infrastructure.

A more fundamental problem seems to me to be what I call "Internet Pollution". There is a huge amount of junk out there with almost no mechanisms to weed out the junk. Maybe we need a "Best Before " compulsory metadata field.

So far researchers, coders and hackers seem to ignore the polution problem. We treat the Internet like we treated the Oceans.
