Sorry for the delay.

I briefly looked into the netstat approach but pretty much ran into a
wall.

The problem is that I need to display the delta between two successive
counts .. which means that I need to store the i-1 values of my byte
counts somewhere they can be accessed next time around.

Can't seem to figure how this could be done .. either in awk or with a
mixture of bash and awk.

Closest I've come to a solution requires temp files .. real ugly.
