I'm sure someone has already thought of this, but I just set up a 
delegation system for SPF records.  When SPF returns none, I lookup the
domain under _spf.delgate.com to see if one is supplied.  This lets me
supply SPF records for use by my customers for domains which won't provide
them themselves.

There has been talk of such stuff at various points in time, but it
has generally been concluded that any public list would run into
liability issues.

The current Perl implementation (Mail::SPF::Query) has an override and
fallback option to support this kind of thing on a local basis.  The
(soon to be released) libspf-alt v0.3 has similar functionality.
