Bitwig and Presonus have worked out and open source standard to connect work done in one DAW to another. They call it DAWProject.
Here’s an article that goes into some detail on it : ( you can click English on this )
And good information from GitHub :

And a short intro from Presonus :

Lots of potential here if other DAW makers get on board.
It looks like some people are in process of adding Reaper to this.
I could also see the potential for some software makers to put together a simple template generator sort of app, or some utility to strip down already generated projects and create a core template from those as well. Potentially with this sort of code you could move parts around between projects, let’s say that come from different places, and maybe not even from full DAWs.
Also @Ryan – I think this might fit with your scripting idea in this thread. Just the whole potential for synchronize projects could be an interesting offshoot of DAWProject.
