I'd be worried about just switching RPi's off. We recently got a Pi for the office to run as a dashboard - and after a couple of power cuts it corrupted the SD card.
Now I'm going to have to set up the system again, and I don't know whether this is going to happen again. The SD card that got corrupted was a Class 4 Kingston.
Maybe I'll look into a Sandisk (possibly Class 10?) next time. But I am worried that it's not the SD card's fault, but rather a combination of a journaling filesystem, an SD card and a sudden power outage.
Edited: Apologies, I realized now that the red button cuts power to the network switch, not to each individual Pi. But my concerns about the Pi and power cuts still remain though.
