I'm not from ISC as well, but as Eivind has already stated - BIND 
already supports EVERYTHING there is on DNS server/resolver side. It 
serves SPF records, allows to fetch them, and there's nothing more from 
DNS you can require. What remains is *mailserver's* side to query for 
said SPF records and act accordingly. And this does not belong to ISC, 
but to your mailserver's provider. Postfix can do this by external 
plugins, some others probably as well but I haven't tested it.
