Our team always used to hit the edge cases quickly... Some technologies might be there for years, but when we start hacking, we'll immediately come across a situation that might faced only by veterans. Our experience with Delphi (one of the coolest technologies), ASP.NET MVC, MonoRail/ASP.NET, iPhone/Android programming proved that. This time, with another new technology... fingers crossed...
I personally find that Xitrum Scala framework ( readme ) is more appealing or easier (to build fast) than Play!/Scala. It looks like Play! 2.0 will fix the gap .
