It's an interesting proposal.  We could use a separate zone line
tld.surbl.org to get the info out.

Another, possibly better, approach would be for me to use the
same ccTLD routines that Eric is borrowing from URIDNSBL on the
data engine side.  That is another way to get us all in sync
assuming that approach used is reasonably sound.  It's something
I may check out later.  Until then the ccTLD list will need to do.
