Email Riddler Question

Script: Email Riddler
http://www.dynamicdrive.com/emailriddler/

This script looks like it will be great for my site, but I have a question before I dive in. I see the script information says you CAN use this script multiple times on the same page. My question is, can I use it MANY times on one page? I have a school reunion page where I post contact information for people in my class. I want to protect their email information. Will I have problems using this script more then 50 times on one page? What can I expect? I am not experienced in using scripts.

Thanks in Advance!

It uses document.write(), so too many applications are likely to slow down page loading time considerably.
