Yeah, after I sent the email and went out for a few minutes, I
realized I could do this:
                final Decorating decorating =3D new Decorating() {
                    public void decorate(Object instance) {
                        System.out.println("HELLO " + instance);
                    }
                };
                pico.addAdapter(
                    decorating.createComponentAdapter(new
NullComponentMonitor(), new NullLifecycleStrategy(), new Properties(),
moduleClass, moduleClass, null)
                );

... as you might guess, I'm not too happy about the CM and LCS bits,
I'd like to "get them" from my current pico.

Not really (although I haven't given it much thought), the components
I'm decorating have no specific interface or annotation to
differentiate them, they're just registered from a different source...

Ha cool, no more 404 images ;) Had been a while since I seen it. HA!
and I see the navigation changed. I'm still kind of missing a high
level navigation, either on the side or the top, though.

Excellent, thanks !
