About the error and warning rate:
I would hope that one day bind/named (and the rest) would verify the SPF
record(s) syntax. Catch the error at the source!
Maybe this is un-likely until SPF has its own record type (which I hope will
happen one day).

Subject: [spf-discuss] Observations on SPF record publishing in .edu
I decided to do an informal survery of SPF record publishing in .edu
domains, specifically US colleges and universities. I chose this group
partly out of personal curiosity and partly because it is easy to find a
fairly complete list. (Yahoo is pretty reliable on colleges and
universities.)
This was not a carefully designed or carefully recorded survey, but I came
away with some impressions I think are accurate.
1. SPF record publishing is not concentrated by region, state,
administrative unit or religious affiliation. Non publishing, although
harder to judge, also appears unaffected by the same parameters.
2. Total SPF record publishing so far is a small fraction of all the
colleges and universities.
3. Most SPF records are published by small to medium sized institutions.
The big exceptions are UC Berkeley and Columbia
4. Private, church affiliated and public institutions are all publishing. I
would say that the private and church affiliated schools are somewhat ahead,
in percentage, of the public institutions. This may be secondary to size.
5. Schools well known for computer science departments are no more likely,
perhaps somewhat less likely, than others to have published. This may also
be secondary to size.
6. "Technical" schools are no more likely to have published than general or
liberal arts curriculum schools.
7. Probably 2/3 of institutions with spf records have registered them at
http://www.spftools.net/register.php before I got to them. (I registered
the ones I found.)
8. The error and warning rate appears higher than recorded at the registry.
Most of the errors have been typos or simple omissions. A couple indicated
serious misunderstanding of the syntax.
Conclusions:
1. SPF record publishing is probably being decided on a one by one basis,
very likely by very small groups of people, perhaps only one, at each
institution.
2. People composing records are not as likely to use the wizards and
validators as one would like. Essentially all of the errors would have been
caught by the online tools. None of the records appears to have come from
the faulty Microsoft wizard.
