kalmia had two aliased interfaces (209.234.73.40, and 41), and was
responding on the .40 address.. so I could see it locally, (cause it had
the same mac), but those packets didn't get back to me.

I got burned by short hostnames ('kalmia' vs 'kalmia.hozed.org') a

What kind of issues would a IP-NAT box introduce? I think this may have

some issues when untarring the kernel..
