BBCode Ajax test server

Since I have some time on my hands, I've been doing a little work on Postmarkup - my BBCode module. I've made some significant improvements to the design which fixes a few issues and makes it easier to create new tags. To test it, I hacked together a simple web-app using CherryPy, which allows you to edit bbcode in the browser and see the resulting html update live -- with a little Ajax magic.

Please give it a try, and let me know if you can break it.

In building this, I've created a very rudimentary web service. I'm wondering if there is any practical use for such a thing...
