If you want it to look as close as possible to that then I would use a module like Ventrian's Child Links - there are one or two others around that are similar.

The trick is to use multiple copies of the module on the same page. Set the starting level of each module to the root tab of each different site section. Combined with ZLDNN's module wrapper to contain each major section in 3 or 4 columns, this will give you pretty much exactly that... but no guarantees, as I haven't done it.

No I dont' recall specifically, but I have a feeling that one of the free ones was actually posted on Snowcovered, so have a look there - sort by price from $0. Also browse the modules, links/navigation sections. However, dont' shy away from buying a cheap module, and Ventrian's modules are well worth it. Personally I wouldn't lift a finger to do a job that wasn't worth spending 20 bucks on.
