Make sure you change the TTL's of at least the affected records, then
wait for the old records (with the old TTL's) to expire, then change
the addresses.

Certainly. AppleScript. I don't have a ready-made script for this,
but a minor change to one of my existing scripts will do the trick.
Go here:
<http://interaction.menandmice.com/applescript/display?recid=2>
Copy the script and paste it into Script Editor. Change the first
line: What you want to set is the "Minimum ttl" field, not the
"Primary" field. The value you want to set it to is 300.

Yup. AppleScript again. Try this one:
<http://interaction.menandmice.com/applescript/display?recid=5>
You'll need to unwrap some of the lines, though. If you're not
keeping the last octet of each address constant, but are using a
pattern, you might try this one instead:
<http://interaction.menandmice.com/applescript/display?recid=4>
If there isn't a simple pattern that you're using, then you may have
to change one address at a time (not one A record, but all A records
pointing to a given address), using this one:
<http://interaction.menandmice.com/applescript/display?recid=7>

Correct. We use a binary format that isn't easily modifiable using
BBEdit. This format makes parsing zone files much quicker, meaning
that server startup time and folder scan time are much shorter.

One at a time, unfortunately.

That depends on exactly how many occurrences of each address, how
many zones, etc. In other words, that's up to you to decide. But the
AppleScript solution is probably the least work.

Yes, we haven't changed the format too much. It would cause problems
with regard to your QuickDNS Options file, but you could just trash
it afterwards.
