Commercial show matches.

No, I don't think it's necessary – there are actually plenty of good players who could do two-sided commentaries. The quality of such restreaming, in my opinion, largely depends on the commentators – few people can properly explain all the moves of pro players. I was thinking about doing a restream of some microgames myself about a week ago – I chose 2-3 of the most interesting games, there were microgames available, but unfortunately, I didn't have time to start before the beginning – and I didn't want to restream games from the 13th, so finding the streams themselves isn't a problem, the problem is catching them in time. I think that creating some kind of closed section where the approximate start time and stream numbers of players would be posted would be a big boost. But you can't force people to do this, and instilling such a culture takes too long. Some enthusiast could certainly take on this task (asking players in private messages when they have roughly agreed on a time, and then posting the numbers and updating them). But, in my opinion, enthusiasm won't last long. Although, for example, during the World Championship, many games were restreamed in two-sided commentary thanks to Sticky. I would also like as many players as possible to do streams. You can easily do your own things in parallel – just switch the scene in XSplit, for example. And for streaming Heroes, 800x600 resolution is enough with a dual-core processor 2.5 GHz+. I (and I think many others) can help set up the stream.
