Well I think routing over areas sucks, and I would not support it. There 
should be clear distinction between ares and highways as lines for 
routing. If people want to have areas instead of lines, they simply 
should think up another tag, but not use highway.
If you have on your way say 10 places where it should route over, it 
will start to fall into pieces, as it is too complicated for the 
algorythms to route over areas - even if only alongside the borders.

BTW Minko, please check you e-mail client. Your not properly replying 
but writing new topics. This is a pain in the ass.
