Portable Body

Martin Fowler talk in this article (“http://www.martinfowler.com/articles/mobileImplStrategy.html” )of portable body (slide 23). He talk thinking a web, i instead think to Qt/Qml, where Qml is the native gui and c++/javascript is the portable body. Is exsisting a benchmark between qml/Qt vs Hybrid(web+native; javascript+native) applications? For me this is an interesting point. If someone wants to help me in this comparison, I would be happy.
