IIP Image zoom plugin

Has anyone successfully installed an IIP Image viewer? Here's an example of IIP in action on our Dspace server. http://drc.wooster.edu/handle/2374.COLLW/6561

The problem with Microsoft Zoom.It is that it requires silverlight which unlike Adobe Flash, is not installed by all users.

I'm pretty sure end-users can view Zoom.it images without having Silverlight. I don't have it and I can view the zoomable image on Microsoft's site and have done so also on some Omeka sites using the plugin.

I think Microsoft's official line on this is that Zoom.it "enhances the experience with Microsoft Silverlight, when available."
