I was pretty sure the answer was NO, and hence google gears, adobe AIR, etc.

If I was right, then how does http://tiddlywiki.com work? It is persistent and written in javascript. It is also just a single HTML file that has no external (serverside) dependencies. WTF? Where/how does it store its state?

Tiddlywiki has several methods of saving data, depending on which browser is used. As you could see in the source.

If ActiveX is enabled, it uses Scripting.FileSystemObject.

On Gecko-based browsers, it tries to use UniversalXPConnect.

If Java is enabled, it uses the TiddlySaver Java applet.

If Java LiveConnect is enabled, it tries to use Java's file classes.
