Many months ago I played around with the ESP8266, I found that most shipped from ebay had "incorrect" firmware on them. They came with some sort of demo as opposed to the serial controlled firmware that most commonly is used. If you try them, it would be a good idea to make sure that you have a way to flash them with the correct firmware (a 3.3V usb to serial adapter will do). I also had found that the (now ancient) version of the AT/Modem firmware had issues being a WIFI host. I couldn't get any of my devices to connect reliably, however that probably was for the reason James listed (no onboard DNS server).
