I still prefer hand sewing the binding to the back, but I did experiment with machine binding after a friend told me how she was doing hers. She machine sews to the front, then zigzags the raw edges with fusible thread. She then carefully presses the binding to the fusible thread on the back, making sure that the edge just overlaps the seam line made when she sewed the binding to the front. Then she machine stitches in the ditch on the front. Since the binding is fused to the back, the stitches just catch the binding at its edge.
I tried this method but didn't have any fusible thread, so I used a glue stick to hold the binding in place on the back before stitching. The results were pretty good for the first time trying a new method.
