I would first like to thank the authors for describing their work in a language approachable also to those that are not steeped into novel web-based technologies. The submission is timely and is extremely well-suited for publication in an interactive format. Finally,  I couldn't agree more with the last statement in your conclusions: As a community it is important to embrace open source, open data, open standards, and open access to reproducible research. I think your work does represent an important step forward in this direction.
