Convincing all domain owners to add an SPF record to each of their
domains is quite a task, but asking each domain owner to add a SPF
record to each host in each domain is futile.
I assume that people who manage more than a few hosts do not edit the
zone file by hand! They use a tool like h2n so, for the tool, adding
one SPF record or 1000 is not a problem. h2n already adds a MX per
host, so adding a SPF per host would be a small change (if people use
h2n and do not know Perl enough to patch it, just ask on the list and
I'm fairly certain you'll receive a patch within hours).
