Close.  Very close.

No, zone.192.168.  Your zone.192.168.0 file is for your QA network.

Now negative TTL, not default TTL.  The default TTL is that $TTL macro
up above.

No, this is the most important part:

	// 16-bit zone, not 24, and we don't use the subnet mask!
	zone "168.192.in-addr.arpa" {
		type master;
		file "master/zone.192.168";
		...
	};

	...

	zone "17.168.192.in-addr.arpa" {
		type master;
		file "master/zone.192.168.17";
		...
	};

	// pretending that you had an "NS flame" for subnet 0,
	// and flame is a slave ...
	zone "0.168.192.in-addr.arpa" {
		type slave;
		file "slave/zone.192.168.0";
		masters { IP.addr.of.qans.qa; };
		...
	};

	// etc.

It is in the zone.192.168.* files that you will have your PTR records,
just as you currently do!

Please note: the NS records listed for the child in the parent domain
MUST match those in the child domain.

OBTW: search in the archives for something with a name something like
reverse DNS tutorial.  If you can't find it, I'll re-post it.
