I am *currently* creating an extension to SORBS which will allow ISPs to 
register as whitehats along with their mailservers and netblocks, and a 
fast response email address.

The idea being if a mailserver is about to be listed they will get 24 
hours warning to avert the listing.  If addresses within their netblocks 
get listed they will get notification mails, and the host is listed 
immediately.
