Nobody needs it right now, but once most people have the option of it, new ways of needing it will appear. This would be great for cloud computing with family videos or games that you rent online which stream all the content directly from the servers. With the rise of IPv6, it could also lead to the development of a more distributed web content model where people host a lot of their own content for others to access and browse using personal web servers instead of P2P clients, since pretty much everyone will have the extra processing power and bandwidth. There's a lot of uses, and many of them could easily become the new "needs" of the future.
