I didn't mean it to take that tone. I didn't understand what you were
trying to propose. I assumed that either (a) I was missing something
obvious or (b) there was an implicit assumption somewhere in your
statement that I didn't pick up. It looks like you were talking about
filtering IP directed broadcasts on routers destined to _your own_
customers. I hadn't picked up on that. I thought you were just going
to be dropping broadcasts crossing your network. (period)
The first, dropping broadcasts destined to your customers, is possibly
doable, but not trivial. The second, catching all broadcasts coming
in, out, or just passing through, is pretty much impossible.
