In the mean time I'll try to implement Leaflet

I could help with that, if you want. I'm not saying I'm an expert on Leaflet, but I experimented a lot with it.
I saw you use a kml file to load the rectangles. Leaflet doesn't have kml support built in (yet). One way to solve that is to use geoJSON; or use an external kml script (but I didn't test that last one).
