Yes, I think _I_ would make these configurable parameters. On my
network, I wouldn't have to wait that long. On other networks,
NIS servers might be overwhelmed, or other factors, that would
necessitate a different timeout and number-of-broadcasts values.

Well, the _clients_ broadcast, but I don't think the servers
do?
Hmmmm, elevated privs - do you need root privs to broadcast? I've
never touched that sort of thing myself.
