Sheez mate, anyone can do it the easy way :)

Seriously, thanks for the suggestion.

For posterity and anyone else who might want it... incomplete, rough as guts, 
but does well enough for me:  (ok, it's not one line...)

    #! /usr/local/bin/bash

    # Find sending addresses from SPF for given domain as $1
    for f in `dig +nocmd $1 txt | sed -n '/v=spf/ {s/.*v=spf//; p;}'`
    do
         case $f in
                 include:*) $0 ${f:8} ;;
                 ip4:*) echo ${f:4};;
         esac
    done
