I'm using an Alpha PC164 with two Adaptec ANA-62044 quad 10/100 
Ethernet interfaces as a router. A fine little box, so far.

One frustration I have is the lack of tools (so far as I have been 
able to find) that will tell me what the instantaneous bandwidth 
consumption is through each interface, e.g. similar to what the Cisco 
"show interface" command shows. I know that we collect byte & packet 
counts per interface, so it should be a simple set of changes to 
netstat or systat to show bytes/sec or packets/sec measured over some 
interval (or since boot, since we do have the data...), plus error 

Is this useful enough to the community at large that I should dive 
into either (or both) of those programs and write the code?
