Is it possible to simultaneously flash multiple chips OTA? I'll soon be prototyping 5 ESP8266's which will all be running the same program and I'd love to be able to just flash them all at once instead of rewiring my UART cable 5 times every time I need to flash. >.<

To do OTA programing you have to establish (in your case) 5 pseudo serial ports and then flash each in-turn. No need for any physical connection with the ESP. I'm not aware of any sub-net programming techniques. I have covered OTA programming in one of my videos and supplied the extra code needed to achieve it (very small source code stub), see here to help out: https://www.youtube.com/watch?v=ZVA1pV6WUQg
