[ishiguroJSK]

Latest broken openni2_tracker package with NiTE2 is modified and available on Ubuntu14.04 ROS-Indigo now.
Be careful about you have to get NiTE2 library file in other way and put it into this package

I found ros-drivers/openni2_trakcer is worth to keep using, since there is already nice contribution for publishing tf -> ros-drivers/openni2_tracker#3
Based on that, I confirmed

1. install nite as deb package -> Re-releasing Nite2 as debian package ros-drivers/openni2_tracker#4 (comment)
2. compile openni2_tracker with rewrited version of #3 (continued porting to NiTe 2 (Status: all tf sending)) ros-drivers/openni2_tracker#8

works well, so please double check if they works on your machine too,

please also check if they are able to run with openni2.launch, and also pleease check if we can use https://github.com/jsk-ros-pkg/jsk_roseus/blob/master/roseus_tutorials/src/kinect-model-viewer.l
