swingarm mounted license plate bracket

Has anyone tried using one of those swinarm mounted license plate brackets? I've seen em on H-D's and sportbikes, but not on any vintage bikes.
I'm doing integrated tail light/turn signals, and would like to keep the tail as clean as possible.
I saw it on a Sportster Nightster I was talked into test riding this summer and I thought it was a neat feature (it folds back to the frame when not being used).
Any ideas, or brackets you've used that you like, or don't like?
All these parts just can't get here fast enough. Before I've even got one thing here, I think of something else to do.
At least my wife is being supportive for now. I guess I could be doing something worse with my time and $$$

I used a bracket and mounted my plate to my grab rail hole just in front of the original TS location.

Keeps it up out of the way and it doesn't have a chance to drag around left hand corners.

If you scroll down, you can kinda see it in the left side pic.
