I agree with sinanju. In this situation I dont have a real stimulation to buy a license because I pratically have all the features that I'd like to have and I'm already fine with BlackWood track and the 3 demo cars.
If demo were replaced with a "S0" license with same contents like current demo (but with the possibility to have 15 players on the track xD), I would be the first one who would buy it.
In this way a new concept of demo should be thought, though.
And regarding that russian website, yeah, it's really a shame that it exists.
I see that InSim sends the Closing Speed for contacts between two cars and contacts between car and objects, but there isn't this information in case of contacts between car and walls.
I'd like to have this information to know the "intensity" of the contacts also in these situations
