Or a virtaul console tyoe thing like vmware-server-console.
Its really cool. You can add a card to nearly any machine to get this.
Only problem is it requires another IP address and ports.
You could re-direct ports from one IP addrsss to another behind a NAT/firewall setup.
IOW, port 9999 to port 1024 for the remote console... etc. 10001 for the remote websetup... etc.
Various options exist.
