Yes, that's correct. We are currently just trying to manage clients
from the Ghost Console, which uses multicast, and we haven't yet
attempted to do anything with the GhostCast server. Ultimately, we
would like to use the GhostCast server, however.

In any case, it's helpful to know that directed broadcast probably
won't be an option because we would need it enabled in multiple
subnets across campus.

Thanks, Ken and Kevin, for your responses.
