I know Spamhaus doesn't offer a BGP feed of the DROP list.  Has anyone 
made a homegrown solution?

"DROP is currently available only as a simple text list but may be available in the future by BGP, announced via an 
Autonomous System Number (ASN). DROP users could then choose to peer with that ASN to null those prefixes as being 
ranges for which they do not wish to route traffic."

I considered giving it a shot until I read that.  It doesn't seem very difficult but don't have the free time to work 
on things that someone else claims is coming.  I also don’t have a spare ASN to share it externally which would be the 
ultimate goal, like the Cymru bogon peering.
