At the moment, I am more interested in writing the Kdenlive side of the
communication than the server side, probably because I am eager to get to a
point where we can say "here is Kdenlive Version 0.x, Here is Piave version
0.x, download them and enjoy" :-)
I was going to write the Nullcutter reference renderer afterwards.
The other point is that I am a little concerned about the scene generation at
the moment. I was expecting a small performance hit for transfering across
the network (and I believe that this is just a small performance hit), but I
wasn't expecting the generation of the entire scene list to be _quite_ as
slow as it is at the moment :-)
I think it may be necessary to add a new command "updateSceneList" which only
transmits the modified sections of the scene list, rather than transmitting
it fresh on each generation.

Great! Sorry, but I have never looked into Xv extension.
