Perl and Permissions on Windows

Hey,

I have a slight problem...I have installed the latest version of Apache on
Windows XP Home and ActivePerl. I am looking to server as a small web host.
The problem is that users will be able to upload their own perl scripts and
using the open command, would be able to see and modify the entire hard
drive. Is there any way to restrict their access to the disk to that they
can only view and modify in their root directory. It is a NTFS drive but
there is no security options installed (ie you cannot specify file
permissions).

Any help would be greatly appreciated.
