I find your concept very interesting and ready to subscribe to have access from time to time to a strong analysis machine. However, there are severe limitation in the interface :
You give only the only move, it would be great to display the full main variation (it is in the logs but not user friendly).
Also while analysing, it is great to have multipv mode up to 5 variations so you can understand the difference between the different options.
One very good interface is http://analysis.sesse.net/ . I would love to have such interface to analyse my games and happy to pay for that.
Have you plan to improve ?
