I like the thought of using a smartphone, since it wouldn't require a mod. My thought for a use-case would be to do some simple "mode changes" on the fly for the pineapple. In addition, seeing the target environment in a small, possibly integrated, display seemed like a useful addition to have an all-in-one device. I'm guessing that all that could be done with a smartphone, but I was concerned with adding concurrent connections to the one wireless interface available on the pineapple.
