Bruce -
Glad you liked it. I have to say it was hard work keeping with everybody when they split up, and i was worried about keeping everyone entertained. Still, that's the fun of playing chaotic goblins. All I can hope is that everybody else liked it as well.
To answer your questions. Yes - the scenario is one of my own. I like to write new scenarios for every con. Is it online? Unfortunately no. The scenario would need work before I could put it out. Currently the encounter notes exist as one file, while the layout of the necropolis exists as handwritten notes in a little black book. However, if you want the details, give me some time and I could write them up.
Ironically, one of the scenarios I intend to run at at Games Expo I am planning on putting out as a pdf when I can find some illustrators. My own artistic abilities are limited to piloting CAD programs and very bad sketches
