What's wrong with UPnP?

@allenbretao, I wrote about this here:

As for licensing, we’ll figure that out as time goes on. Right now, we are working with select partners we feel will both benefit from RoonSpeakers and where we’d benefit from their audio expertise. RoonSpeakers is to be built into the device. If users don’t use Roon, they won’t know anything about RoonSpeakers. If they do use Roon, they will take advantage of the benefits RoonSpeakers provides.
