Who is willing to write a tool to do broadcast address discovery and access-list generation? Ideally with a config file that would allow one to avoid serious self smurfing (ie, ranges to check and patterns to assume are broadcasts without trying them).
Filtering broadcast addresses is pretty ugly. Consider that a single Class C broken down into /30's can have 64 broadcast addresses. Maybe if it was just filtering your own assigned subnets, it would be possible, but this also applies to customer-subnetted broadcast addresses, so you'd have to coordinate your filter with every one of your customers, every time they change subnets. Not impossible, but pretty close.
