Any other zoom feature plug- in other than ?

Hi Everyone,

I was wondering if anyone else have tried any other open source zoom featured plug-ins beside works great and I love it. However I'm building arts collection at my college, that will be only available to students on our campus which does not meet with User agreement which says :
"Your Application and content in your Application must always be available publicly without restriction (for example, login or password must not be required). You may not host any Application which uses the Service in an environment where access to such Application is limited to an internal audience within your company or organization. Please utilize the standalone developer controls provided by, Silverlight and other APIs for development on non-public sites."

If anyone have tired anything else besides please let me know.
I would appreciate your help
