Well, if the router CAN run BGP, the feed from Cymru is only about 84
prefixes - not a lot of memory tied up there, is there?
If the router isn't capable of BGP, someone earlier today was kind
enough to post a script that they use to find changes to one of the
BOGON lists and suggested an Expect script to automatically update their
router. Probably a little advanced for most leaf sites, but for someone
who's responsible for a larger network -- doesn't seem that bad.

How would this scale for say 200K routers? 2M? -Hank
