Not widely used.  Also, Yahoo, who started DK, doesn't even do its "ADSP" extension coding correctly:  They have an entry but CNAME it to something that never resolves to a TXT-RR, so it's broken.  Some other domains do it correctly, but I see it in perhaps one of 50 transactions at most.

It's much harder to set up.
