Hi Guest,
Take a look at Tiddlywiki.
"It's written in HTML, CSS and JavaScript to run on any modern browser without needing any ServerSide logic. It allows anyone to create personal SelfContained hypertext documents that can be posted to a WebServer, sent by email or kept on a USB thumb drive to make a WikiOnAStick. Because it doesn't need to be installed and configured it makes a great GuerillaWiki."
I've played with it a bit in the past and it seems like it might fit the bill.
