That's not really fast flux.  FF uses TTLs of just a few seconds with
dozens of NS.  Also, in practice, most FF NS are invalid.  Not that FF
has
a fixed definition...

www.yahoo.com.          24      IN      CNAME   www.yahoo-ht3.akadns.net.
www.yahoo-ht3.akadns.net. 57    IN      A       69.147.76.15

akamai, 60 second TTL's... most of the FF things I've seen sit around
300seconds for NS and for A records. either way, this is 60 seconds
which is fast enough.

Interesting, I was under the impression anything less than 120 is
effectively as good as 120.

I have not measured... I bet yahoo has though :) and/or Akamai.
There's a reason that these folks are doing this. Would be an
interesting presentation though eh?
