well, you have a bunch of options, depending on the
specific usecase ... e.g.
- use a real console (serial or vga)
- use a virtual console
- use a pipe or unix socket
- use a network socket

AFAIK, there is no constraint on private IP addresses
(yet, although the IPV6 folks would like to see that
on IPV4 :), so the public IP address constrains are
not a real reason for not using ssh or telnet

maybe I should rephrase my original answer and state
here that 'vserver - enter' (for good reason not called
logon) is not really a logon to the guest, instead it
moves the current process into the various namespaces
and contexts, making it 'look' like a process which
runs inside the guest ...
btw, personally, I don't see why there should be an
additional way to logon to a guest, compared to a normal
host system, but definitely there should be a way to
do some emergency repair and testing until the guest
is perfect (at which point the enter is not required
anymore) and a quick and simple way to utilize the
guests as advanced chroot (which the enter can be
considered, although I would wish the 'running guest'
limitation would be dropped there, in util-vserver)
