i am confused as to why anyone would want to make a setup like this, unless they were being shady. if you are going to be installing a transparent filter/proxy/etc., shouldn't you have enough control over the networking environment to work around the DHCP problems? it seems to me that working on the setup as it is currently posited is a poor time investment. i would think harder about how to change other things to work around this issue. unless, of course, you were being shady ;).
