What about the client that sits on a saturated 10/100 Mb Ethernet
subnet? Where his or her throughput is directly related on how many
co-workers are at their computers. BTW, when is this measurement /
indicator set? Is it at initial connection time or is it based on the last
few packets that have been sent? If it is the later then the indicator is
a very moving target that might make a server balk, especially if there is
a persistent connection between the browser and server.
