[Screeninvader] how to trigger servside actions

[Amir Hassan]

I had some thoughts about the screeninvader web api. especially about how  
to trigger server side actions.
e.g the webinterface can delete the playlist with following actions:

janosh remove /playlist/items/.
janosh mkarr /playlist/items/.

you may notice that this is by no means atomic an can lead to strange  
situations. that leads me to my idea, which is simple: don't allow any  
actions from the webinterface except publish and implement lua scripts the  
wait for the message (e.g. playlistClear) and perform it in a safe manner.
can you come up with any actions that cannot be handled that way? a case  
where we would need access to all the other janosh functions?

anyway i would even disallow a direct get action, which would lead us to a  
situation where we could finally implement ACL - in lua.
