The active/inactive palette api and visual appearance is designed for showing 
enabled/disabled controls within a window. Hence, text becomes grayed out and 
less readable which doesn't matter for an inactive control, but it does if 
you are trying to read text in an inactive window. All the active/inactive 
window visual metaphor is supposed be doing is to say 'if you type a key on 
your keyboard it will go to this window', it isn't trying to say 'you 
shouldn't really be reading this text' on inactive windows, as grayed out 
would indicate. 

The X-Window window manager is more primitive than the Mac OS X one, and we 
have to be careful to stay within it's limitations. The flashing re-draws etc 
that people have reported, just can't be worked round easily. Then there are 
the networking bandwidth problems, incompatibility with other toolkit 
problems, that people have discussed on this thread.

Well I'm still not convinced it is technically possible.
