I guess I'm thinking of a scenario with a dedicated blackhole triggger-router, iBGP from the trigger routers to routers within my own network where I want to drop traffic, and eBGP multi-hop from the trigger route to each of the appropriate routers on the upstream transit networks.  No need to worry about the RIB on the trigger router, and community-based tagging and filtering can ensure that these particular blackhole routes never make it into my own routers in my own iBGP.
