Just wanted to let you know that I've pushed the API/UI app up to heroku so you can start hitting it with benchmark scores here: http://ruby-bench-staging.herokuapp.com. It's on the free plan so there are limitations but I am speaking with a couple of the guys at Heroku to see if we can get some sponsored hosting for the production environment.
I've popped up some sample data to check that it's all working. An example cURL request is in the readme of the app repository.
Any problems, just let me know.
