You might want to go have a look at comp.dcom.lans, where 10BaseT (standard
twisted-pair Ethernet) has had considerable discussion of late.  This isn't
really a Unix or TCP/IP issue.

(To sum up the c.d.l discussions excessively tersely...  10BaseT works well.
Relative costs are somewhat debatable; there is no huge difference, but
thinwire may still be somewhat cheaper.  10BaseT is parsecs ahead on
reliability for complex networks with large user communities, because
its star topology tends to localize failures to a single machine, whereas
thinwire takes down a whole network segment when one ignorant clod unplugs
or damages a connection.)

There are slower twisted-pair technologies in use, but 10BaseT is Ethernet
in all respects as far as performance goes.
