29 //todo: make real daemon out of it- systemd conform
30 //todo: versioning of PluginInterfaces on linux level (.symver stuff)
31 //todo: all communication like all plugins loaded etc...
32 //todo: seperate documentation of test from normal project
33 //todo: check the startup sequence. Dbus shall be activated last...
34 //todo: there is a bug in the visible flags of sinks and sources. fix it.
35 //todo: make sure that iterators have a fixed end to prevent crashed while adding vectors while iterating on critical vectors
36 //todo: make sure all configurations are tested
37 //todo: clean up startup sequences controller, command and routing interfaces----
