[lug] A question!

>Isn't every network a "contention system?"


No. Fast-ethernet (100FD) is not.  T1 lines are not, etc.  It's how 
you hook them together that creates the 'neck.

There are low-level hardware topologies designed to avoid contention. 
If you design networks to scrub that then that's a design choice.
