Like many others my first thought was to have a way to reach underneath to open the drawer. A music rack made about a decade ago used this method:

There is a rail under the drawer bottom to allow a finger hold for moving the drawer.
My other thoughts were of either reaching over the top to push the drawer out from the back or using rods and/or levers to start the drawer out.
