It think, VP shines in specialized fields and not general programming. Visual domains are an obvious example. If your domain is constrained by something that maps good to spatial dimensions than you're good to go. A few extra dimensions can also put into styling. But after that it becomes too restricting. That's why interface builders work fabulous until you have to implement actual business logic and modularize your application. This always leads to adding things that aren't directly represented in the current visual model and get lost, because of indirections.
