As a fan of Justin Hileman's Genghis, a single-file MongoDB admin app, I originally intended to contribute a new UI with the profiler results, but one night was not enough time to wrap my head around Backbone.js and develop the query aggregation. Instead, I whipped up a quick frontend using the Silex PHP micro-framework. But with the hack day deadline no longer looming, there should be plenty of time to get this functionality ported over to Genghis. Additionally, the map/reduce JS may also show up in Tyler Brock's mongo-hacker shell enhancement package.
While presenting mongoqp to my co-workers, I also learned about Dan Crosta's professor, which already provides many of the features I had hoped to implement, such as incremental data collection. I think there is still a benefit to developing the JS innards of mongoqp and getting its functionality ported over to other projects, but I would definitely encourage you to check out professor if you'd like a stand-alone query profile viewer.
As for MongoQP, contributions are welcome through Github.
