Need a system to pull demo blocks into jQuery wiki doc pages

Right now, we pull in a bunch of static wiki doc pages directly into the UI site like dev guide:

http://ui-dev.jquery.com/docs/Developer_Guide

Since the wiki html examples look terrible when pulled in, we've been removing them but we need a way to add demos to pages. I'd like us to create a simple comment token that can be 'silently' added to the wiki docs pages. The token could just give the name of the demo to insert, like this:

<!-- insertDemoBlock path="demos/effect_types/effect_all.html -->"

This token would be parsed when we pull the page into our UI site template and would AJAX in a demo block in the token location, just like the other demo page.

I'd like to get this built ASAP so we can include this demo page:

http://jquery-ui.googlecode.com/svn/trunk/demos/effect_types/all_effects.html

...as a block here:

http://ui-dev.jquery.com/docs/Effects/Types

This would require some tweaks to the template file that processed the docs. Anyone want to give it a try?
