Another Prop module idea

Does anyone know how to do castellation in a PCB layout? I rather like the SparkFun Bandicoot Protoboard, but the layout is not useful for QFN or QFP modules. Could a prop module be made with 100mil x 50mil pad spacing to solder straight to such a board?

    A castellation technique I once considered is to put a row of plated holes along the edge, and have the board cropped so that the holes are cut in half. I've never actually tried it, though.

    I think that the proper way to do it is to have the edges plated.
