wow, that's a killer app. i've been playing with it and it looks like it
should do the trick. thanks for the tip.

the only thing i'm not sure about is where exactly the domain names will
forward too. the rinetd app forwards all incoming traffic to the IP i
specify. so, if i have a site called 'acme.com' on the original box, a
request comes in for that site and rinetd forwards the request to the
specified ip address, does that mean that the new server will serve up the
'acme.com' site, or the default web site?
