It'd be nice if DHCP could be replaced/augmented with a sort of virtual clustered host, where one half of your cluster was you mobile PC, and the other half a virtual slice of a server, supporting the same IP and name all the time. We could call it a cloud or something.

ftpaddhost
ftpaddhost(1M) System Administration Commands ftpaddhost(1M)
NAME
ftpaddhost - set up a virtual FTP host
SYNOPSIS
ftpaddhost -c | -l [-b] [-x xferlog] hostname root_dir
DESCRIPTION
The ftpaddhost script is executed by the super user to set up virtual FTP hosts. The ftpaddhost command configures the virtual host host-
name under directory root_dir. The value of hostname can be an IP address or the name of a host.
OPTIONS
The ftpaddhost script supports the following options:
-b Create a banner for the virtual host. This option is useful to confirm that the virtual host is working.
-c Configure complete virtual hosting. This option allows each virtual host to have its own version of the ftpaccess,
ftpconversions, ftpgroups, ftphosts, and ftpusers files. The master version of each of these configuration files is
copied from the /etc/ftpd directory and placed in the /etc/ftpd/virtual-ftpd/hostname directory. If the
/etc/ftpusers file exists it is appended to the virtual ftpusers file. If a virtual host lacks its own version of a
configuration file, the master version is used.
-l Configure limited virtual hosting. This option allows a small number of parameters to be configured differently
for a virtual host. See the virtual keyword on the ftpaccess(4) manual page.
-x xferlog Create a logfile entry such that the transfer logs for the virtual host are written to the specified file. An abso-
lute path must be specified for the xferlog file.
OPERANDS
The following operands are supported:
hostname The host name or IP address of the virtual server.
root_dir The absolute pathname of the directory under which the virtual server is set up.
EXIT STATUS
The following exit values are returned:
0 Successful completion
1 Improper usage of the command
2 Command failed
FILES
/etc/ftpd/virtual-ftpd/hostname The configuration files directory for the virtual host hostname.
