On this topic I'd like to share gist-txt[0] a tool I created to build text adventures starting from markdown files hosted on GitHub's Gist.
It doesn't need hosting as your files will be hosted by GitHub and you can write your interactive fiction stories directly form the web.
It uses mustache templates and JavaScript to achieve minimal interactive functions.
I wrote a little introduction[1] at Ludum Dare's blog and I will use it to write a text adventure for the AdventureJam[2] starting next week!
Note: I took inspiration form Twine[3] and bl.ocks.org[4] for the initial development of the tool.
