If you're going to create all those alias IPs on the loopback, why not
just run a named on each of them directly?  No need to worry about port
translation then.

Setting up aliases is easy enough:

seedling:~:% sudo ifconfig lo0 inet 127.0.0.2 alias
Password:
seedling:~:% ifconfig lo0
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
	inet6 ::1 prefixlen 128
	inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
	inet 127.0.0.1 netmask 0xff000000
	inet 127.0.0.2 netmask 0xff000000

(deleting one is just: sudo ifconfig lo0 inet 127.0.0.2 -alias)

	Cheers,

	Matthew
