The proper answer to this is to disable directed broadcasts on the routers themselves. It'd be helpful if routers came out of the box with this feature disabled by default. Perhaps folks should talk with their router vendors of choice and ask for this change. I have submitted a draft into the IETF process to require this change, updating RFC 1812 (router requirements).
I'm happy to say that progress is being made in this area. When a vendor comes to us for the first time, one of things I tell them is that we will not buy their hardware until they ship with directed broadcast disabled by default. We've had a lot of success in this area, we'd have even more if others would do the same.
