Wiki on a Stick (in short WoaS) is a wiki that lives in one self-modifying XHTML file. It's perfect to be used at home or at office, on your laptop or USB pen drive (along with Portable Firefox if you want) and even in a floppy disk! It can be used as a personal notepad, calendar, repository for software documentation and many other things; it allows full customization and extension by your own scripts or libraries. It also offers true AES encryption of pages.
