Will this be available in 2.70?
I am working on it. Why are you asking?
Congratulations, CND, your patch just got comitted! Blender is compiling right now. Thank you again for your work!
Thank you, Sanne. Great to see my work in a build-bot version! Hope you will use it a lot! 
Thank you very much! Good team work “easy to synchronize bevel and path animation” --> to make it really easy I should work a bit more. But at least it’s possible now!
