No, that was CallerID, later SenderID.  SPF was from Meng Wong at 
POBOX.com, based on the work of others.  The MARID working group tried to 
merge SenderID with SPF, but that effort failed.

SenderID was a bloated mess of XML jammed into DNS TXT records.  Sometimes 
EDNS0  (if it was even available) wouldn't keep it from failing over to 
TCP for the DNS query.
