All the Debian ISOs are isohybrids, so
cat debian.iso > /dev/sdX
and you are on your way to a no fuss installation. A simple one line
easily remembered command. Couldn't be easier.

I'm rather fond of GRUB's loopback mode but the netinst ISOs or CD-1 are
not geared to being booted in this way to allow a normal install to
proceed without the user intervening. An inexperienced but willing user
trying it without detailed instructions would likely end up saying
'doesn't work'.
Technically you are correct; if you can manually mount the ISO held on
the device you can continue. But with hd-media the mounting is done for
you from within d-i as a matter of course, so why bother with the extra
steps of mounting or bindmounting. I do not consider loopback mode (the
subject of the mail I replied to) to offer any advantage over this
method or the one described above.
