Everyone in favor of SONOS developing a speaker for exterior use?

This would be great. I ended up getting a Sonos that I use in a covered patio in the yard. I keep it in a pelican case in good weather when not in use. When it is wet (I live in Portland, OR) it comes in the house where it is dry. A more permanent option would be great.

100% YES! During our outdoor speaker selection and setup for our pool area last year, we had to "settle" for conventional outdoor speakers connected to a Connect:AMP. I would have preferred spending money on an extension of our Sonos speakers systems for outdoor use instead of buying a Connect:AMP and finding good outdoor speakers to pair it with.

I'd buy two and permanently mount one on my front porch and rear deck.

I can't see such a speaker coming into existence. Too many limitations due to the player(s) being located quite far away from either a) the customer's main router or closest AP or b) the closest other zone player in Boost mode.

Then there's the problem with full waterproofing (preferably with an IPxx certification), battery life, general 2.4GHz signal stability outside of buildings due to interference/noise, limited multiroom ability and so on. Sonos works great in stable in-house network environments but was clearly not designed for establishing long-range wifi communication spread over several access points. The complaints would be endless.

A simple near-field solution like Bluetooth would imho be the smarter way of approach. But then again, such an approach doesn't have anything to do with the Sonos multiroom concept.
