Build it. I'm in.

Some less effort would be nice indeed. I'm sceptical though if what you describe would be the right mix. Untouched RAW are not what I'd like to share with peers.

I just find the actual camera software to be much better on the phone and often times produces a nicer image when shot right alongside my actual camera.

Will be interesting to see what's next on the market. Especially in terms of versatility and compatibility with third parties.
