Fortunately I am a network pro. :)

we go in and provide solutions to D&B/F1000 companies, most have legacy wiring systems (beware the closet...) that cannot be easily upgraded. They are in essence stuck with 10 megabit 10baseT or even thinnet cnx for all users. Sometimes a backbone upgrade can be done (usually FDDI, not fast ethernet, so at least the fiber is there for the future) but it gets very expensive.

Network World ran a survey a while back showing most corporate nets run at average saturation rates of 40% on their network. People love using their PCs and being "their own little island" when they want to be, there is no way without major infrastructure changes that companies will reach network nirvana.

The whole home race is a magnification of the problem, to rewire homes to use fiber instead of copper delivery (excluding cable systems, if they work out the upstream bandwidth problems) would cost approximately 400 BILLION dollars...

btw, file server saturation and link segmentation are really big problems that cannot be trivially dismissed. Distributing file servers across the domain is a nightmare, especially since virtual-switching still hasn't made inroads. We checked out the recent cabletron MMAC offerings, it was a joke. Their "virtual circuits" just did packet routing, which congested the network even worse!!
