[OS X TeX] final tex live 2007

[M A]

Now that Tex Live 2007 is official (as of the last day or so), I'm
thinking of installing it (my current tex is a few years old now). I
have a couple of questions, though, for which I would appreciate
answers to, if anyone could be so helpful.

1. Is the Tex Live 2007 at http://www.tug.org/~koch/NewPackages.html
the same as the one from CTAN? (That is, were there any changes made
between 2/12, when I think the one at ~koch was made, and 2/20, when
the final official release went out?)

2. How literally true is "unmodified" in the "full TeXLive
distribution from TUG, unmodified, 618.4 MB" statement at ~koch? The
CTAN package is some 900MB, but the koch one is 600MB. Is this only
because non-Mac platform specific stuff was removed (and some
compression differences between dmg and zip)? Would the installs from
either source really result in exactly the same set-up with respect to
binaries linked from /usr/texbin, the maze of links in /Library, the
distribution preference pane, TEXMFHOME being ~/Library/texmf (I
thought Tex Live uses something like ~/tex by default?), etc?

Thanks,
Mark A
