So you'd choose a random device and broadcast out? (lo0 anyone?)

And even broadcasting out all devices is most likely not the right
thing to do. (pppoe0? Or what if more than one device is connected to
the same network segment?)

But what if you want to talk to all hosts on device ath0, regardless of
their network mask?

You can't cover all situations, and you can't even cover one
appropriately. Hence my suggestion that using bpf is the sane way to go
here.
