Minimal
Notice the L-shaped 3-pixel (OK, 4 techincally) boxes on the top-left, bottom-left, and bottom-right corners.
Top-left:
left-click: tasks
right-click: custom programs menu
Bottom-left:
left-click: command line and winamp controls (LSXCommand 1.8.4, dynamp and skinbox--skinbox so I can use PNG files, which doesn't seem to work for label)
right-click: system info (label and MBM)
Bottom-right:
left-click: system tray
right-click: full "start" menu

Litestep 2.4.6-something, latest stable indie build, using the remnants of Simplicity so I don't lose functionality as I get my theme working properly.
