wmmenu is a "dock application" for Windowmaker that provides a button bar to launch applications from. The bar opens automatically when the mouse enters the button. Multiple instances of the program can run at the same time; each one provides a menu that it reads from a separate file, so you can have as many different menus as you want.
wmnet polls network statistics and does a few things with the data it gets. It has small blinking lights for the rx and tx of ip packets, a digital speedometer of your tcp/ip stack's current speed and neatest of all, a bar graph like xload et. al which has a tx speed graph from bottom-up and rx speed graph from the top-down. The speedometer keeps track of the current speed per second and shows it in a color corresponding to which of rx or tx that has the highest speed at the moment.
wmnetload is a network interface monitor dockapp for Window Maker. It is designed to fit well with dockapps like wmcpuload and wmmemmon. It tracks whether the interface is functioning and displays current network interface throughput, along with an auto-scaling graph of recent network activity (the graph separates upstream and downstream traffic load cleanly without resorting to colors).
