No it doe snot download. Binaries are pre-compiled. Compatibility
we try to achieve by compiling on relatively old machines and linking
many things statically (as many as possible). But
still there are always some cases where it does not work out.

No it is not downloaded.

install-tl installs both binaries and other files (the main support files).
THe distribution size is maybe 90% *NOT*-binaries.

Which "support" files? All the other files from TeX Live? THey come
from CTAN (with a few exceptions).

WHich support files, again? THey are taken from CTAN and installed in
the proper places, this is human job we (mostly Karl) is doing.
We have some automatization, but human intervention is still

Building from source??? From which source? Just download what is on
CTAN, maybe run it through a variety of latex/pdflatex/makeindx/etc
invocations. THat is *building from source* for TeX/fonts/latex/context
etc files.

Maybe you spare us and yourself a lot of time and just state what you
want ot achieve?
