In the very early days, of com skip I stumbled across a beta.tablotv site from some real old posts. You could enable comm skip for testing. There was an actual playlist you could stream via external players, asked a 3rd party developer about exported commercial free video. Post marked 
as well as site.
Last time I had looked physically at a drive (some time ago) it seems they now have a times list for the player to skip. Not actual new playlist, just a JSON file with timing for the player. I’m sure it’s makes sense to say it’s a new playlist.
This was during the free trial, after the beta… after it became available for the web app. I don’t access to com skip so I can say how it may have further evolved on the local side. I did look promising when we stumbled over the skipped playlist, using it for exporting.
