Christopher, thank you for a great link.  I have been looking for a long
time for something to run on a lan to test different branded NIC drivers and
switches.  This should support LAN speeds.  Look forward to trying out
"Advisor" and "JPerf" along with it.

There is also a promising Bandwidth Meter project at Georgia Tech:

SmokePing http://oss.oetiker.ch/smokeping/index.en.html is a project that by
default would not take up much bandwidth.  The ping payload may be
configurable which could possibly be adapted to test bandwidth.  It can also
work with Nagios.
