The new features in the CVS that we outlined in the October report might replace this stride bone method, but that doesn't make this tutorial obsolete as its a very informative mountain of information overall and will get you a bit more prepared for using the new features and is helpful in getting to know IPO manipulation as well as animating in general in Blender.
Especially if you are one who waits for the official release ofthe next version of Blender, and doesn't dive into the CVS, then this tutorial is definitely for you. At 30+ pages in length its quite a read.
The author quotes on the tutorial:
This tutorial is meant to supplement the already existing Blender documentation which can be found at: Blender Foundation Advanced Stride Support Documentation I assume that you have already read this document (even if you didn't fully understand it). Hopefully, this tutorial will provide some additional practical experience using the Stride Path feature.
