A very strict javascript lint (verifier).

JavaScript minifier - available as MS-DOS exe, but also in C, C#, JavaScript(!), and Python!

Laudible but difficult to acheive goal of building a trustable "zero-knowledge" pure javascript program. Current browsers just have some many ways to unintentially run code that isnt' "reviewable" by the user.

I think it's a fine idea to encrypt locally, and store only encrypted data. But I think in practice, the user ends up having to trust the entire system of components - including the server. He can't, after all, do a complete security review every time a new version of the javascript application is loaded from the server.

Quoted: A zero-knowlege web application knows nothing of its users and their data. This is a first definition of a new methodology.

JS-Kit is probably the closest thing to what I've been working on for PageForest. I'm impressed by the 1/2 million sites figure (though many of these are probably very low volume blogs).

Quoted: JS-Kit will leverage its newly acquired users to launch important new features. One of which is the implementation of an open standards-based, portable, user profile.

IE has a subtle bug when parsing array constants - I think they are not in conformance with the ECMA-262 spec.

Update: Object initializers are even worse! Fails to parse the JS at all.

Quoted: JavaScript Persistent Object Notation (JSPON) is a convention for using JSON to facilitate JavaScript referencing and complex object types to provide the necessary semantics needed for efficient and meaningful persistent objects.

I'd like to use the Summize API to build a nice Twitter widget in StartPad.org.
