Of course. :-)

It is possible by using a virtual node "connected" to the
ISO file. Without having tested, according to your example:

	# mdconfig -u 0 -t vnode -f /hd1/Downloads/FreeBSD/9_1/FreeBSD-9.1-RELEASE-amd64-disc1.iso
	# mount -o ro -t cd9660 /dev/md0 /mnt/tmp
		... do stuff ...
	# umount /mnt/tmp
	# mdconfig -u 0 -d

An alternative would be to use tar to extract the files from
the image, change whatever you want, and use mkisofs afterwards
to rebuild the (new) image, in case you want to modify its
content.
