I've looked at a few of them, and I noticed that all the ones I've seen
start with the four-octet string "00 00 00 02".  Is that sufficient?

I'd recommend checking the next four octets as well; they'll be "00 00 00 00"
or "00 00 00 01".  The first of those is the format that's always been used
up to now; the second is the format that will be used in 9.9.0, starting
with the next beta.

Ho hum... does this mean that if one has been running a 9.9.0b(next) or later
and let it generate master files in the new raw format (e.g. as a result
of dynamic updates), then one would have a problem backing off to earlier
BIND versions?
