You have quite a lot of room for expansion with ethernet. My home network
consists of a linux fileserver/internet gateway connected via 100baseTX to a
switching hub, which is connected to two other PC's, and a 10baseT hub via the
uplink port. This hub connects to another couple of slower PC's, and also to
the original 10base2 coax I put in some years back, which links in a RiscPC and
an Alpha box. In addition I have two laptops for roving use connected to the
fileserver via radio ethernet.

It's a somewhat odd installation, and took a little fiddling to get working
correctly, but is that way because it sort of grew as my requirements expanded.
As well, I never throw anything away.

Everything works pretty well, and is reliable. A MK.II would simply plug into
either of the hubs.
