Changes
== Current issues ==
* The telepresence part dosen't work* OK Accelerated video decoding and display on the Raspi
* PTL outgoing bandwidth
* Build a wooden window-like frame with curtains
* gstreamer-omx crashes way too often!
* We're now using [https://www.linux-projects.org/uv4l/ uv4l] instead of gstreamer and it looks quite promising!
== Hardware ==
* 2 (4?) Raspberry PI
* 2 Camera modules
* Custom printed box

== Automation with Puppet == The basic idea is to develop are shared puppet recipe hosted in a git repository to allow multiple raspi managed by different entities to all share the same verified configuration. This will hopefully provide insurance that the system really works point-to-point and that there's no way to spy in-between.
