yesterday I got my N950 devkit and at once starte to port one of my apps. Using the qt-creator it was really easy.... at least so it seamed. My app listens for multicast messages. The code work fine on N900, Linux and OS X, but the N950 seems to be multicast deaf.
The N950 is so new I feel a bit ridiculous to ask if someone has experiences with multicast on this device, but one never knows. :-)
