I've used a slightly modified version of this script to implement something
similar:

http://horde.net/~jwm/software/misc/comparison-tee

It uses the pcap library to sniff traffic sent a live server, then forwards all
packets to a test box and compares responses. You can modify it to reply
saved data too. It also allows you to exclude some attributes from comparison.

Adding the attribute to pass client ip address to the test server won't be hard to
do.
