That would be nice to have :)

plugin.deactivate doesn't work while freevo is running. I wanted to
implement it for some time but I did not see the urgent in this.
But there is get_ressource() in application. Right now it is used so
that audio player and video player know that the other one is blocking
the audio device. I guess this function would be a good starting
point. Right now only applications can block a ressource, we need to
make it possible that plugins can do, too. get_resources returns a
dict ressource name -> application of all ressources blocked. In a
perfect world get_resources returns an empty dict. So what we should
do: joystick plugin reserves the joystick ressource. Now games does
get_resources('joystick', 'video', 'audio') and the return is {
'joystick': JoystickPluginInstance }. This means audio and video could
be reservered (but are not because not all ressources are free). Now
games has the plugin for joystick and can call a 'pause' function and
the joystick plugin releases the joystick. The next get_resources
would return an empty dict, games can start. After games is done the
games plugin calls 'resume' on the JoystickPluginInstance.
I just moved get_resources and free_ressources out of the internal
code and accessable for everyone. So the joystick plugin should do
get_resources('joystick') in __init__ or plugin_activate. If the
return value is not empty it is an error. The plugin should have a
pause and resume function calling free_ressources and
get_resources. You can access this fuctions through the application
module: freevo.ui.application.get_resources.
Hope this helps.
