Recording the performance NOT the audio

I would like to see a new feature in Mixxx
Recording the performance NOT the audio

I have three user cases:

Case 1:
you use Mixxx to compose you show and you then can email/upload the file
the receiving party can play it live or they can up-render it (save to a file at their requirements, eg 48k, stereo, FLAC compression level 8)

Case 2: AutoDJ:
the more that you use this feature the more the autoDJ can use what has learned to create a mix in your style
(highly unlikely to be done)

Case 3:
record keeping for the royalties collecting societies for Case 1
