There are Android apps that can stream to AirPlay speakers.

There are also windows and Mac software to stream from desktop computers to AirPlay speakers (Airfoil)- so I don't think making an airplay speaker would seriously limit your audience to just Apple people. I was shopping AVRs recently and it seems everyone except Onkyo is building in AirPlay functionality.

Definitely no dock. I want to control the music from the phone/device in my pocket. Gotta love the clean, no dock, no controls look. Plus docks only tie you down even further to a specific device/brand.

What about a ported VP 150ish kind of design? I would put that in my living room. Maybe a hair less wide for WAF.
