Power a two in one

[icecycle66]

Is this how I should wire power to run these two Stage Fright's at the same time?
Or, do I need to do some more complex power managment?

(I'm not going to bother with a battery clip.)

Personally I would take a 100R from the 9v supply to each "red" power line.
Unless there is already one on the board, in which case ignore me.

I havent read the build doc for the stage fright
