Deaggregating for emergency purposes

I am currently announcing only my aggregate routes, but I have lately thought about the possibility of someone mistakenly, or maliciously, announcing more specifics from my space. The best solution for an emergency response to that (that I can think of), is registering all of the /24's that make up my network, so if someone should announce a more-specific, I can always announce the most specific that would be accepted (assuming they don't announce the /24's too, it should be a problem avoided) Does anyone else have any other ideas on ways to quickly deal with someone else announcing your more specifics, since contacting their NOC is likely going to take a long time... --Phil
