Interesting artcle...
I've had a quick hunt around on google and found nothing, but you might want to check some of the comments - plenty of people seem to have had a go at implementing a simple component demo, you might want to take a look at some of theirs for inspiration:

Also, the comments themselves seem to have a fairly in-depth discussion on how you might code up such a system.
