Applet content accessible by URL

Hi all,

I want to know if there is a way to access content generated by an
applet/xpcom-component/embed-tag using an URL.

The idea is to use the src attribute of an img tag to access an image
generated by an applet.

If not I think we could use some kind of virtual protocol like the ones
used by KDE.

For example: <img src="mozilla-jndi://applet1/image1.jpg" />

Thanks.
