Is it possible to install a custom class loader for java applets in the browser?

Question

I'll first admit that Java class loaders are a bit of a mystery to me.

What I'd like to do is define a class loader that would load any applets the browser encounters. I know I can modify the policy file to grant elevated privileges and install a custom loader inside of an applet. What I'd like to do is change the default class loader so that any applet is loaded through my loader.

Are there browser or plugin specific settings I could modify? Could I write my own browser plugin and configure the Java plugin through some API calls?

Thanks!

It looks like you can set the property java.system.class.loader property in the JRE runtime settings to replace the system class loader.
