Easy - for example i have my own TCP acceleration solution, which is using 
REDIRECT, then getsockopt/SO_ORIGINAL_DST to get original IP, then forwarding 
to compressed tunnel, stripping unneeded bytes (oh, my expensive satellite 
bandwidth). This way for example i can do some kind load-balancing for 
satellite bandwidth. But i have done it over -m statistic.
