Have any of those libraries been audited so far? Seems like a necessary step for widespread js crypto.
Oh yeah, and before people with torches show up, let me clarify that is a Javascript based crypto product but not browser and website based crypto. The deployment target is situations where the code delivery problem is solved: HTML5 mobile apps (including phonegap / cordova), desktop apps with things like AppJS, browser extensions, etc. It's a high level secure-by-default framework for building collaborative realtime and storage applications. Javascript is a natural language for this, because the framework provides storage through an object database, and that approach is natural an convenient in Javascript. We're spending the time and money to make a secure framework now so we don't have to spend quite as much time in reinvention and security review for each new crypto application we build.
You should ping me via email if you're serious about arranging for OSS crypto to get reviewed, not because I want to sell you audit services, but because someone already beat you to the punch in a big way, and you should talk to them. :)
