Checking the SS catolog, I see that it is being marketed for "...repetitive drilling operations or for controlling 'stopped' operations..." That about covers what you are using it for now, but...
An additional use for them: SS also offers an extension for their Miter Gauge that uses a similar stop. It may or may not be the same flip-stop. If it is, then you could add additional stops for multiple set-ups.
I can think of another use for them: A person making his/her own sliding cross-cut table or sled could build a fence (adjustable for angles if so desired) that could utilize a flip-up stop, or more than one, again, for multiple set-ups.
Well, thats what I come up with. Hope it helps.
