Okay, I managed to fix the namespace errors, and now player creates a file called position.pioneer2at_model::position_iface_0 in /tmp/gazebo-xx-0.
So, now I am able to subscribe to and command the position2d:0 interface, but when I try to move the pioneer using my mouse in the playerv window, nothing happens. I'm just wondering, is there a position3d interface available that I should maybe try connecting to? Position2d just doesn't work. Works in Stage, though. Hopefully someone can suggest something...
