Federation with funkwhale

[petitminion]

I've been thinking of extending the federation capabilities between Peertube and Funkwhale.
Funkwhale is specialized in audio content. I was wondering if we could request a audio content from peertube, using musicbrainz id ?
This would require to implement musicbrainz id into peertube and to add api endpoint to get only audio content (either a list of video that are audio videos, or directly an audio stream)

We also could implement federation the other way around : get audio content from funkwhale network into peertube.

What do you think ? Are you interested ?
