Yes.  Maybe in combination with the "iprev" method explained in
http://tools.ietf.org/html/draft-kucherawy-sender-auth-header

Whois is a minefield, IMO the last thing a DNSBL BCP needs is to 
explore whois ratholes.  I hope John's technical draft makes it
*before* the BCP.  A DNSBL BCP will run into serious trouble, no
matter what the authors say, the topic is controversial.

Thanks, I didn't know that.  I can't say if it's still up to date.

Embarassing, I don't exactly know how "whois.cymru.com" does its
magic, but rxwhois outputs the result after checking some DNSBLs
for a given IP.
