And if any of us can RELIABLY exceed 30 percent usage on 
an Ethernet network, I want to see it.

For networks, plan on using about 10 percent of the available
bandwidth in your capacity planning and you should be safe.

For 10 Mbit Ethernet, figure 100 KB/sec, 
for 100 Mbit Ethernet, figure 1 MB/sec,
for 1 Gbit Ethernet, figure 10 MB/sec.

If you are using a network switch instead of a hub, that helps, 
but it is still better to be on the safe side and plan 
conservatively.

As always, your mileage may vary ...

I don't believe this is quite correct.  Thats a serial protocol, and 
AFAIK it still uses start and stop bits, so the real /8/ divisor 
above should probably be /10/, giving a 10 megabytes or 100 
megabaud a second rate, hence the naming convention.
