OT?: non-root use of mount to loop mount filesystem images?

I hope this isn't too far off topic. I figure some of you may have
attacked this issue before:
Does anyone know how (or if it is even possible) to allow a non-root
user to configure and mount a loop device to whatever mount point
they choose?
On my development machine I typically do not login as root for the
obvious reasons. But to mount a filesystem image with the command
below I have to be root:
# mount -o loop=/dev/loop0 rootfs.image /some/mount/point
I'd rather not have to 'su' everytime I need to mount a device.
Using fstab to allow non-root users to mount specific devices is less
than ideal for the above because it "fixes" the mount point to a
single location. And worse, it still requires root to set up the
loop device with the losetup command.
I thought that if I gave my non-root login read/write access to the
loop devices, then I would be able to mount them as non-root. But
even with access to the loop devices mount fails with "only root can
do that."
