Transparent proxying in 4.x with squid and ipf?

[Jim Hatfield]

I used to do transparent http proxying with ipfw and Squid,
but lost that when I switched from ipfw to ipf. The Squid
port Makefile says:

>#    This option does not work on FreeBSD at the moment:
>#
>#    --enable-ipf-transparent
>#     Enable Transparent Proxy support for IP-Filter systems (incl 3.0)
>#     (IPFilter headers are not currently installed to the base system,
>#     PRs ports/60700 and misc/44148 describe the problem; see
>#     http://www.squid-cache.org/Doc/FAQ/FAQ-17.html for information
>#     about how to do transparent proxying with ipfw)

Is this ever likely to be possible again in 4.x or will I have
to wait for 5-STABLE?
