Denon, depending on what the Sonos API has to offer your time to capitalize is running out!

Due to the Sirius/XM streaming change you are ripe for picking up tons of LMS swap outs. BUT, the integration with RTI is only just so so and your reliance on DLNA is holding many of us back from offering your solutions.

I have a LINK in my own system that replaced an LMS setup. LMS is a superior experience within RTI. I would assume that would be true of all 3rd party control.

We are begging you guys to provide us with a solution. So far it looks like the solution you are providing us, is to kick Sonos into gear and publish an API.
