Aye! The way I used it when tinkering with Peertube (not making the content to make it worth keeping things going yet) was to set up secondary Peertube servers dedicated to this function to spread the load across multiple servers rather than use the p2p side of things - I wasn't sure of the GDPR implications of p2p It worked really well at least at the small scale I was testing with :)
