NodeToad

This program has been designed to run in the menubar and to display ADSL data usage, NodePhone (VOIP) usage, as well as providing links to Internode websites and a built-in radio player to listen to quota free streaming radio stations.

NodeToad is completely customisable, so you can have just text in the menu bar (such as % of total quota used), an icon, or a whole range of different menu widgets.
