The lines above merely create a temporary environment for generating
formats and mapfiles. The real configuration takes place earlier, by
writing to the registry. I tested things under Windows XP and
Windows 2000, and in those tests a re-login was sufficient.

I am working on a web page about portable TeX Live and MikTeX, with
revised scripts and howtos. It might be useful to include a
zero-config solution where you start up a command prompt or an
editor with the right environment settings, somewhat in the spirit
of your Emacs solution. I would have to test how much functionality
could be made available this way.

I had something in mind that I can give to people for use at
arbitrary locations, so that is why I prefer to put in some tests.
Adding Ghostscript and an editor is the right idea. But for an
editor I would pick something like TeXnicCenter, which has a wider
appeal. And personally I wouldn't worry too much about dvi viewing
if Ghostscript is available for converting to pdf.
