"There are > no logs about who is sending what, and that is a good thing". that's not strictly true. as long as you restrict your network to plan 9 machines, it is possible to import /net from a gateway machine and avoid sticky things like packet filtering. there is also ipmux (discussed in ip(3)). i don't think ipmux has enough rewriting (or state) to implement something like nat. - erik
