BIND has supported the SPF-RRtype since the fall of 2006.  Even RFC 4408 itself declared the use of TXT-RR's as temporary until its own RR-type was allocated, of which the IANA notes was done in late 2005.

Considering all the bugs, exploits, and other issues (such as DNSSEC implementation in the DNS root and elsewhere), if one can't afford to upgrade his software to something reasonably current, such boxes don't deserve to be on the Intenet.  I stand by my statement.  Being at least aware of current events is every system adminstrator's responsibility.
