Hei Tarkam : Actually what you said, the remote control is one of our targets since Canola 1, as we dreamed about the contextual interface : car, home and pmp.

The thing is there are a huge numbers of server side solutions, and most of them are not so well prepared for the real end user.

That's why we chosed UPNP. Our goal is to not only stream from, but also control and in the end, even serve music to your desktop pc then goes to your music system.
So imagine that you came from work, with a new file on Canola, then you can play it on your internal sound system without even need to copy the file.

The problems /drawback : Sonos is a great idea, I have been looking / checking since the launch, but they work because they are selling the whole solution, and even connecting to a music store. For us with just a client.. is really hard to trust a lot of servers, and users are kind of not so "used" to them. Having PS3s, or Windows media with UPNP can help but still complicated : /
