How to remotely reboot halted Pi

Question

I'm thinking of building an array of Pis but I'd like an intelligent method of powering them, i.e., I would like power to each to be controllable via USB. I like the USB GPIO Module suggestion given here, however, I would like to know if the reset pin is an okay method of starting the Pi assuming it was properly halted.

The other method I considered was using a USB-controllable power strip, but the reset pin method sounds much cheaper if it's okay.

It seems the answer to my question is here. It's apparently a yes. :) — hfaran, Nov 11 '13 at 11:18
I will add a detailed answer once I actually build the setup and can confirm it works (the method I am referring to is this). It may be a while before that happens though. — hfaran, Nov 11 '13 at 19:41

There isn't actually a pin, but there are two holes at P6 on the rev. 2 board (~1cm left of the HDMI jack) that if shorted together will reset the power. You can attach a switch to this.

Indeed. I was thinking of using just the GPIO Module suggested in the other question, or even another Pi/Arduino. (That is, make a simple switch circuit using a transistor like the one here, and then using whatever to control it to boot the Pis). – hfaran Nov 11 '13 at 19:40
