Amen...

Well, it *would* help detect an intruder that's smart enough to  subvert the
signing of the zones on the DNS server, but unable to also subvert the copy
stored on some FTP site. Rather esoteric threat model, fast approaching
the "Did you remember to take your meds?" level.

Plus, if you're worried about foobar.com's zone being maliciously signed, do
you *really* want to follow a pointer to www.foobar.com to fetch another copy? :)
