I am interested in this.  I did a wee bit of looking around and
couldn't find much about %CD%.  I guess the idea is that if the
shortcuts are in the FWTools directory, then when you click on them
the %CD% will be the FWTools base directory?

Perhaps the setfwt.bat and openev.bat could check if %CD% is an
FWTools base dir (by looking for %CD%\bin\setfw.bat for instance)
and if so, not do the hardcoded directory thing, but use %CD% instead?
Would it be helpful if the installer left a copy of the short cuts in
the FWTools directory?

I would be interested in making small modifications to the installer
if it would make this sort of thing much easier to setup.
