Well this is the idea behind Google Gears, allowing you to locally persist data in a little lightweight db. Normal js won't allow this due to the myriad security issues; with gears the user installs it and allows client side code to access it. But the status of gears going forward is a little unclear, for instance I haven't seen some major issues that cause browsers to hang being addressed.. However the GWT- gears lib is up to date: http://code.google.com/p/gwt-google-apis/wiki/GearsGettingStarted
