I have put together yet another iBurst connection monitoring utility because neither of the existing two I know of would run on my Mac. This application is written in Java / Swing and so should also be usable on Linux, Windows and other platforms. The utility only works with UTDs that are connected via ethernet (with the usual network config rigmarole) and requires the Java Runtime Environment (JRE) 5.0 in order to run. There is a download with a brief readme and a couple of screenshots available at the link below.
Hope it helps
