  I have only 1 router/modem, with 3 machines behind it.  In addition to
NATing my internet connection, the router/modem also handles traffic
between my machines...

  Connecting to the internet uses the same cat5 cable and jacks and NIC
as connecting to one of the other machines behind the router.  What am I
missing?  Is there really an money saved by having 1 Gbit connections
locally and 10 or 100 megabits on the internet side?
