Some new format for DAW session files that is compatible with all DAWs. I believe ardour can import protools files but I bet a lot. Of work went into that.
Nice, hadn't seen this before. From the looks of the Ardour forum there is nobody currently looking at implementing the forum but they seem open to it.
I would contribute but I only know python so probably not much use. I could write a ardour-dawproject translator in python but seems a bit pointless if someone goes and creates a proper implementation at some point anyway
