You can try Namecoin Core (https://github.com/namecoin/namecore), which is based on the latest Bitcoin code. I don't know how to do what you want in Bitcoin, either, but I guess it is possible there.

You never run a node I guess. I have 30 IPs on my server, do you think I want namecoind to listen on ALL of those IPs lol.
You guess wrong, I did run a 24/7 public Bitcoin node for a long time (and still run one that is not always on) and I run two Namecoin nodes publicly. I just don't have servers with 30 IPs.
