Need For Speed Shift is now available on the N950 with the PR1.1 firmware. However it's not part of the over-the-air upgrade. You need a few more steps to install the application:
1. ssh firstname.lastname@example.org
3. apt-get update
4. apt-get install nfsshift
Update, 2011-12-16: Leho has a nice writeup on installing Skype UI on the N950.
