You can find a short story set in the same universe here: http://dir.salon.com/story/tech/feature/2003/08/26/truncat/index.html
It is set an undetermined amount of time after Down and Out in the Magic Kingdom, and the events are independent.

It's a good read, I enjoyed it. Unfortunately, it does leave you wanting more, as the book does.
I wish there was a send the next installment button :p
