A well-behaved proxy should also send an HTTP_X_FORWARDED_FOR header, containing the internal ip address. And it should honour downstream proxies, adding those headers together. So the Static API simply needs the last IP address listed as HTTP_X_FORWARDED_FOR, or the real REMOTE_ADDR if there isn't a forwarded header. In my case (Orange UK phone using Opera Mini), REMOTE_ADDR is the Opera proxy and HTTP_X_FORWARDED_FOR is the Orange proxy. It *should* also have the internal Orange IP address, but it doesn't -- that's probably an error on Orange's part.
