Great, I'll keep you in the loop.

It this point I am exploring the feasibility of a couple of options.
1. Load test suits. Running various simulations that would enable us
to reproducibly load test the server hardware.
2. As you suggest a bunch of VMs on a server. We could direct connect
the VM server to the piece of hardware on which we are testing the
school server using a cable
3. Alternatively, I was wondering about the possibility of a running a
bunch of wireless usb dongles from the VM server so we can get more
realistic wireless network device capacity. Each VM would be running a
dongle.
4. A test bed of actual laptop.

As we shift from option one to option four things get more complex and
expensive.... yet the quality of test will improve. I am in the early
of exploring what is possible on a really tight budget :) Tight as in
if I skip my ice cream cone this week, I can buy a usb dongle.
