Anyone know if the chip can be used as a repeater?

thx

With some creativity it should at least technically be possible, since the ESP8266 can handle AP + STA simultaneously.

Exactly how to get it to forward packets is, of course, an entirely different question. Software NAT might be possible (but AFAICS not through the espconn API), but one would soon run out of RAM. Whether or not transparently bridging the two interfaces is possible at all (without low-level ROM modifications), I don't know.
