there a way to use these two together?
Some background - I'm testin
cool..
Now that you've done it by hand, could you write a script to automate
the tree creation?
(than we could commit it.. )

with ipfw and dummynet to do bandwidth shaping as well as firewalling ...
The machine is a Dual PIII 733 w/1gig of RAM and 2xfxp0 devices ...
