if you're using smtp-auth, what does it matter whether you're roaming
around or not? the mail will still be relayed the "official" mail
server. if they're roaming and using a *local* smtp server then SPF
records are relatively useless.

Unfortunately most folks roam around a bit *and* use authenticated SMTP
(now THAT would be a better standard to push), so their email can have
just about any IP address on the net and still be valid for your domain.
Of course if all your users hang out in the office... and the office has
a static IP range... and all your mail sent from your domain is only
sent from the office... then Heck this will work.
