Sorry I've not yet chimed in on this. My take on this is that live CDs,
while handy teaching tools, do not provide what is trying to be
accomplished. What I, and I think Chuck, would like to see is a portable
demonstration toolkit. Something that a student can build as they go
through the curriculum, much like an artist's portfolio.
Because of the licensing limitations like VMWare, it does not lend itself to
this portable idea.
For the "live data" aspect, I've been kicking around using tcpreplay and a
slim VM to generate this traffic. Worth a look.
