Well, no, they can only use those portions of the network hidden behind
the bridges created by the switch.  Machines that are not participating
will still not be able to network with the machines that are during your
packet storms.  That's not how shared networks are supposed to work.

If you want to blast data at a another machine (or set of machines) at
full wire speed then you should install proper point-to-point links that
can guarantee the performance you wish to see.  That'll let you
eliminate any unncessary overhead inherent in all shared network
protocols too.
