Active layer? (I think if you made all but the active net translucent, it 
would make it harder to figure out where the avaialble routing resources 
lie).

I did think of something along those lines though.. if you were to be in 
enforce DRC mode, you might be able to recolour the legal regions of board 
to route in, or desaturate elements in illegal areas which are fixed, and 
should touch the track being routed.

Since the background (unrouted resource) of each layer is typically either 
black (my colours), white(ish), or layer colour (if you're through 
ploughing a polygon), recolouring legal areas there is difficult. Any 
keepout regions would have to be positively marked.

If we were to implement a "pushaway" mode where routing tracks could be 
made to shove other geometry out of the way, perhaps desaturation of 
consumed resources would only be done for immovable obejcts, such as a 
component, or a locked track.
