ImageJ as applet

Hi,

I have written a plugin to ImageJ.  I'd like to give visitors to my web 
site the chance to test it.  So I'd like to let them start ImageJ as an 
applet, open up some images stored on the site and use the plugin.  Is 
there any way to do this without requiring users to jump over hoops with 
internet security settings?  Do I need to somehow "sign" my version of 
ij.jar?
Thanks for any help
