Yes, that's exactly what we do for the BD jigdos every week.

Nope, that's the hard bit. It needs access to all the needed files.

Follow the code path through the Makefile - we use the task(s)
specified, #including other files as necessary, to generate a list of
all the packages that are wanted (rawlist). That's cleaned up
(genlist), then we sort dependencies (tools/sort_deps) and make
temporary disc trees (tools/make_disc_trees.pl). Once we have the
trees made, we run tools/make_image to actually generate the ISO/jigdo
images as required.

Potentially, but the code to work that way may have rotted since we
don't use it in production. The normal method is to build on the same
filesystem as the archive you're using, then you can use hard
links. There are also some bits of the archive that we need at runtime
that *don't* get put on the CDs/DVDs.
