Hmmm... ok, expanding on that what I was looking for was a means to simulate semi-realtime delays across a virtual network with 4+ virtual machines. Is it possible to use Dummynet in this case, or do I need to look into something else?
Other conditions I planned on imposing are non-locking NFS (causes a lot of issues here with files at work), and have SUSE 32-bit clients (host OS of choice at work) if possible connect to the host machine and with one another, executing make jobs.
Any further suggestions on how to do this?
Thanks,
