I made a couple glass doors for my son's entertainment center earlier this month. I cut a 1/4 groove on the rails and stiles and used short tenons to assemble the door. Before glue-up, I used a straight bit in the router table to remove most of the material on the inside for the glass (the rabbet is the same width as the groove cut for the tenons, I think I used 3/8 but I use 1/2 sometimes if the door is large). It means you have to start and stop on the stiles but that is not too hard. After glue-up, I used a forstner bit in the drill press to remove most of what was left in the rabbet on the stiles and then a chisel to remove the rest. You could do the same thing with pocket screws instead of the short tenons but it would be good to learn to make doors with little tenons like this, they are strong and easy, once you do a few.
I have a rabbetting bit but rarely use it. You still have to chisel the corners and you are limited in width to the range of bearings you have for the bit.
