If enough of these NCs can be sold, they would be inexpensive. In corporate America, companies are building in TRA nets. The big difference is that most of the information stays right inside the company. An outsider on the Internet usually can get limited access to parts of a corporate intranet. However, traveling between the Internet and the intranet data must travel through a 'firewall'.
Firewalls protect sensitive internal records from Internet client software snooping.
Anyone working for these companies would see very little difference in the way they would use an intraNET or the Internet. As you might suspect, NCs run on intranets with ease. A fat client is a software program loaded with functionality. Microsoft's Word 6 would be an example of a fat intranet client. Fat client can do almost anything but toast corn muffins.
