[Request for review] perf.js Initial Thoughts

I am looking to for feedback on the initial design/concept of a framework to test and standardize JavaScript framework performance.
In a nutshell, it takes functions which are common in all of the various frameworks, which are non-standard, and attempts to get a comparison of the same functionaltity and how that performs across the various frameworks.

The way results are recorded is by leveraging the BrowserScope.org project.

So far we have only started with fairly standard calls, and begun to trend them across frameworks and browsers.

I would like to hear the community's thoughts on the concept/mission. We haven't yet considered open sourcing the code yet. 
To our knowledge this is currently not being attempted, but may have been done in the past.

You can read more about it here: http://www.thebitsource.com/open-source/perf-js-a-javascript-library-performance-testing-framework/. Feel free to comment wherever you wish.

Thank you in advance.
