Ros installation without root
I suppose that it happens quite often that people that are working in a closed environment without root access want to use ros. cf.

Installation of wstool and rosdep from source
In our case for ros fuerte for example we ended after 2 weeks of work with a big shell script downloading all the system dependencies (like for example BOOST, Log4cxx, PCL or OpenCV), installing it to $ROS_ROOT/usr and after that building ros form source while patching many CMakeLists.txt files.
I took a look at groovy and suppose that at least the building of ros with catkin should work quite fine due to the fact that building flags can be passed directly to cmake. Now the question:
Wouldn't it be nice for people working in such an environment to get a package manager installing packages from source? This could be then called by rosdep. With this it would be also possible to install ros on every Linux as the native package manager does not need to be called. If there is interest in something like that, I would like to work on such a software package.
