Comment 3 for bug 209691

There is also http://code.google.com/p/libproxy/ that seems to be capable of doing this. But I would rather not want to link against it directly. A simple protocol to call external helpers for this discovery would be my prefered solution (or to call a external lib). This would be useful for cdrom location detection as well, I would like to have HAL here without the need to link against dbus and libhal.
