I will look into making a BT simulator. I dont have enough spare machines
to make a decent size cluster at the moment, so I will look at how to
simulate low bandwidth links between processes on a single Linux box. Not
sure how soon I can get that running though. It would be good to have
replicatable realistic simulations with measures of overhead and timing.
