When I'm designing I consciously ignore any sense of "this is difficult/impossible to implement" and when I'm working with a designer I tell them to ignore development constraints in the design process. Once we have a fina design and it is impossible, sure you can reevaluate, but don't let that influence the initial designs IMO.
