I guess the tc tool would be of use to you. You can do
something like this:
# tc qdisc add dev eth0 root netem delay 100ms
for adding a 100ms delay to all packets. It can be deleted later. tc
lets us do a lot of things. This was just an example. A wrapper script
over tc should be able to do the job.

Nice way to teach :) Hope colleges do something like this. Thanks
