Kinect for Windows gesture recognition

I have been looking at the Kinect for Windows release notes and features, since I want to incorporate gesture recognition in my project as well.

At the above page, the first line mentions that "The Kinect for Windows SDK enables developers to create applications that support gesture and voice recognition, ". Voice recognition API is available with the SDK and readily can be used. However, I don't think there are any gesture recognition APIs available in the SDK. The APIs of Skeleton Tracking are there to be used readily but then they have to be tailored with to get gesture recognition.

I have seen videos of Windows Media Center beng controlled by gestures etc. and other applications too. I wonder if all these applications are custom built and have to write their own gesture recognition code.

Currently, in my project I am using Kinect DTW Gesture Recognition from Codeplex. I am having two issues with this -> 1) Looks very performance hogging, and on enabling this with my app, my app throws OutofMemory exception after some time (PC specs are pretty high). 2) Can't say much about the robustness of the system. Works at times for some people and not for others.

I thought if the APIs would have been inbuilt, it would have been good to switch to these. Are these available or else what's the resolution?
