I don’t think Kumi was suggesting an embedded player, necessarily; maybe just some way to post a “This YouTube playlist is what my character is currently playing in the club” link that stays available in the space, somehow. (Both he and I were at a really fun event in the Cinnabar club the other night with a curated playlist, and the DJ simply repeated the link occasionally for newcomers, for lack of a better method.)
A specialized bot seems like overkill, versus a “whiteboard” or some other way to let folks temporarily tack simple notes onto a space… or using this very forum to post links to event-associated media!
