I compiled the patch with my Ofelia GUI abstractions with emscripten for a website. Only problem is that loading fonts does not work with emscripten (as far as I experienced). I like the idea that users / listeners / viewers can manipulate the score they are experiencing on a website. And perhaps it could also work for small displays attached to rasperry-pi´s. it seems quite responsive on a desktop computer, but not very responsive with a smartphone (touch screen).
