Isn't it the same concept that ORBS implemented?
It is hardly a new concept.  Incidentally, multistage open relays
are also handled by MAPS: they go into RBL.

Note that ORBL corresponds to an "output" zone, while ORDB
corresponds to an "input" zone.  So ORBL is more aggressive 
than ORDB in terms of policy; however ORDB is more aggressive 
in the search for open relays, and in fact is now well over
100,000.

I do not have direct experience with any of them. We are
MAPS subscribers and stick with them, but the real primary reason 
for staying with RSS/RBL for open relay blocking is the requirement 
of actual spam samples by MAPS.  They are very useful to us, when 
explaining the reason for a block to a non-technical person (a 
customer of us, or his/her correspondant using the open relay).
Still, using RSS takes significant human resources to an ISP
and we do a lot of whitelisting on a systematic basis 
in order to be able to continue with it.
