Nowadays, every sicko can buy a .com domain for 9$ or even less.
Spammers buy domains, put correct SPF records in their zonefiles and
throw the domain away afterwards... (just like you did with hotmail
accounts a few years back :-))
So IMHO DNS based spam fighting doesn't work. At least not the SPF way...
Cheers,

Use DomainKeys instead of SPF. DomainKeys serves the same purpose,

And why not using the existing authentication protocol on outgoing smtp
server ? So the sender can use the smtp server of the provider of its
email address from any network and SPF can work without any problem.
Did i forget anything ?
Best regards,
