I've noticed some recent posting on controlling traffic congestion, and so I thought I'd update anyone on this list who might be interested in what has happenned with the Linux Bandwidth Arbitrator www.apconnections.net over the last couple of months. I am starting a serious beta trail with state of Washington Public schools. It is very early yet, but looks very promising that with a few more tweeks I'll have a turn key tool that can be plugged into any network without too much fuss. I do not have all the latest software out at the web site yet as I have been busy fixing and tuning. (Will be updating this weekend) I would be very interested in feedback from this group since you do similar things. So please have a look , try it out , and most of all challenge my assumptions and give me feedback. Thanks Art
