True, but I don't think this will help much in this particular case, as
the original poster wants to control information flow via loopback and
you aren't likely to be using IPSEC on such traffic.  In the absence of
a sk_buff security field and associated hooks for lifecycle management,
I think that we'd have to go with something like the iptables MARK
module, ala LIDS.
