Yes, stolen from your last alpha version.

  $ ls -1 bin/*.dll

I've also stolen the license file COPYING-IMAGELIBS.

What is still missing is jpeg62.dll which we did't include in the past
but I found a Windows dll on sourceforge.  No problem for me to
include it too.

Yes, but it's better to avoid the registry.  Suppose you want to run
Emacs from a USB stick, then you don't want to 'install' anything.

It's already possible with TeX Live.  It's accomplished by a shell
script/batch file which adds the TL bin directory to PATH and invokes
a new shell.  Even Ghostscript and Perl are not installed anymore on
Windows.  Programs which need them  are invoked by wrapper scripts.

Yes, this is what I had in mind, but instead of hard-code the TeX Live
paths here, determine them by using kpsewhich.

On Unix:
  infodir=`kpsewhich --var-value=SELFAUTOPARENT`/texmf/doc/info 
  mandir=`kpsewhich --var-value=SELFAUTOPARENT`/texmf/doc/man 

This would be quite convenient and I suppose that auctex already
determines the path to the LaTeX macro packages this way.

Don't know whether it makes much sense for TL-2008 because it will be
released in a few weeks, but it would be nice to have such a feature
in the future.

It will certainly work for info files, for manpages it is a bit more
difficult because they have different extensions [1-9].  But as I said
before, running TeX Live from a USB stick without installing anything
is a great thing, and it would be great to have a portable Emacs for
Windows too.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
