Hi Chris,

As WCAG 2.0 was entering the candidate recommendation stage in late
2008, we built an experimental tool to collect data on accessibility
support for a variety of technology uses and techniques. While it does
not include the ability to directly compare different techniques, it is
similar in many ways to what you're describing.

Accessibility Supported
http://accsupported.trace.wisc.edu

Behind the scenes, the site includes a basic interface that allows users
to submit test results with comments about what they found. Users with
appropriate permissions can then compare submitted test results with
existing data and collaborate on whether the results should be published.

Jared is right that it's difficult to look at some of this in a vacuum.
It's also a challenge to gather data that is useful over time given the
frequency with which new versions of operating systems, browsers and
assistive technologies are released.

We've had limited resources for further development on this project, but
would be happy to talk with you and others who may be interested in
doing something like this about what we learned in the process.

Thanks,

-Ben
