It might be easier to do this on DETER:


That's a testbed at ISI running an Emulab configured for more secure
experimentation.  Though security is a focus of the testbed, I believe
that the admins of DETER would approve a project to recreate this study
and work out the inconsistencies.  With DETER you could start tomorrow
and have a reproducible collaborative test environment that would
outlast a week meeting at Caltech.

Like all Emulab installations, DETER gives you full root access to the
machines, the ability to load complete kernels on the nodes,  provides
GB/s connectivity between nodes as well as an ns interface that
configures dummynet nodes to provide delay and throttling.  I've used
the testbed a fair amount, and it's tough to think of a better
environment for this kind of collaboration.
