That I understand is the intended use if I can
controll the server(apache2 in my case on dreamhost).
However, I cannot do it.

On the dreamhost setup, I have to either name the
launcher as launcher.fcgi(anything with the fcgi
extension) or put it in a say cgi-bin directory.
Either case, by the time it is called, the
SCRIPT_NAME/SCRIPT_FILENAME would be set to
launcher.fcgi and not the real script which would be
doing the interesting job.

In other words, the launcher(provided in kepler) don't
know what script to run as it see itself as the script
name.

Yes, that again assume the launcher is being called
which would arrange the environment. It is how to pass
this info(what interesting script to run) to the
launcher that is the question. As it is kind of being
"pushed" one level down, IOW, the launcher can only be
the script, not the launcher on dreamhost.

I did some experiment with the fastcgi-magnet which I
have to "re-construct" the SCRIPT_FILENAME/SCRIPT_NAME
based on the one in the environment(passed by the
dreamhost launcher) and the REQUEST_URI to derive the
real script name.
