"Boson" Michael asking Cisco. I wonder why a "Boson" employee would
ask.. I would rather see countless people learning on Dynamips than a
"Boson" simulator...
Also I use both, I have Scott's exact setup at home and a real rack at
work. I can never tell the two apart...
And who cares about mcseworld ?
