WordPress MU

When talking with my sever admin about installing WPMU on our server. And we have a script that needs register globals on so we want to know if we could do the following:

=======================
In the end, you may ultimately need to contact the vendor, and tell them that you are on a server using suPHP, thus directives such as php_admin_value
and php_admin_flag don't go into .htaccess files. Instead, directives such as "register_globals = off" are placed inside a file called php.ini that exists in the
*same* directory as the script(s) that require globals to be off. This allows any local user to override the server's settings in the global php.ini file.
=======================

The purpose of this would be to ask the vendor exactly *everywhere* register_globals needs to be disabled.

For example, if it needs to be disabled for these scripts:
wordpressmu/path/to/script1.php
wordpressmu/otherpath/script2.php

then we know we can create a custom php.ini file with this line: register_globals = off

and place it inside these directories:
wordpressmu/path/to/
wordpressmu/otherpath/

Thanks in advace for your suport

I would do it the other way around and enable register globals for your other script. register_globals is a horrid directive security wise, especially since scripts that require it are usually of poor coding. I believe you don't need to place a php.ini in every directory as long as you put a line like this in your .htaccess
suPHP_ConfigPath /home/user/public_html

Right; but, doing so would likely break other scripts. Doesn't seem like that would be a viable option, we would have to go site by site and script by script checking for issues after the change is made. This is what we are trying to avoid.
