End-to-end transparency means that IPv6 supports peer to peer naturally. That means everyone (students, teachers, parents etc) can talk to each other more easily without having to involve third parties, and can talk to each other from anywhere on the globe. Less mediation, more direct, more distributed.
The death of NAT will mean that more and more stuff will be hosted locally - on teaching machines, student laptops, home PCs, mobile phones. I think we will see fragmentation and distribution of things that are now monolithic. Things like Facebook, Twitter, MySpace and so on will be reduced to special purpose indexing services - or will die. Why use them when you can have all your stuff on your mobile phone, accessible 24/7, wherever you are?
Good points. Leon CERNET2 network engineer http://www.cernet2.edu.cn/index_en.htm
