This technology is specifically intended for third party guys to make speakers which can be fed a signal by the Roku boxes, thus making the signal wireless (you still need power for the speaker's amplifier). The intention is to make Roku the single source for all audio in the room and throughout the house. It is interesting, but Sonos already does to some extent. Home and Echo also allow similar capability if they are the source - syncing speakers, that is. But defining one speaker as "left" and another as "center" and a third as "right" and so on (including subs and surrounds) will be unique to Roku. Their primary target is the soundbar space which is massively hot right now and an obvious financial target. Imagine a Roku enabled soundbar which connects wirelessly to your Roku streaming box and a couple of small Roku enabled portable speakers for "party mode" when listening to music in multiple rooms from the Roku box.
