[c-nsp] free WAN emulation software

[Alex]

Hi there,
M0n0wall http://m0n0.ch/wall/ is pretty good, you can insert predefined 
delay/BW/packet loss on the link if you want to.
All it takes is a cheap PC and bootable CD(+floppy to save the config).
In terms of physical connectivity, you are restricted to Ethernet only.
