For those of us old enough to remember the glory days of Infocom, this comes as wonderful news. I really look forward to revisiting the game and seeing if I still remember how to win (probably not). As an aside, I'm pretty sure I still have a copy of the game for the Commodore 64 somewhere in my basement.
If you can get IIS set up, OpenWiki works fairly well with an Access DB as the back end. I'd switch it over to SQL server - in fact, I did for the one that I'm running at work - but I hear the Access based one is OK for small groups.
