Actually it turned out to be a relatively simple change so I made it.
Place these two files anywhere in your path on Windows XP:

http://batchfiles.googlecode.com/svn/trunk/sweave.bat
http://batchfiles.googlecode.com/svn/trunk/rterm.bat

and at the Windows XP console type

sweave

for further instructions.  sh.exe should no longer be needed so it should
run with a basic R installation (plus latex and a PDF viewer). I will upload
this to CRAN in the next few days but in the meantime its available as
indicated.
