Ajaxian took a quick peek at AMASS, a very much to the point hack, pulling in the Flash persistence framework to your javascript client code, without using any more of flash than that comfy minimum required. Brad Neuberg seems to have this very nice habit of making high quality hacks with high quality docs, under a BSD license.
I'll have to investigate tying this into GreaseMonkey hacks; it feels like this might open up the door to a strain of very interesting client side applications, again quite challenging the way the web has traditionally worked. (Maybe using JSDB for convenience, when the GPL license inherited from TrimPath doesn't matter -- read Brad's amusing bafflement of how JSDB came into existance from marrying these two tools less than 24 hours after he pondered it, for a hearty smile. :-)
