maybe... your question really isn't all that clear.
You might mean with regards to some kind of network remote access to the console head (which would be my favorite guess on this).
In that case, a serial console device is like an Avocent/Cyclades applicance that allows multiple machines to connect via serial cables to that applicance and then you are able to use ssh (for example) to go to the applicance and establish a serial session to the connected hosts. I like this and use this style for a lot of out of band stuff...
Then the IP console solution would likely be some kind of KVM over IP or some kind of access directly to some kind of IPMI like thing (doens't have to be a standard IPMI, could be Sun's ALOM/ILOM, HP's ilO, Dell's DRAC, etc). The IP support through that (the latter IPMI-like case) could come in a myriad of forms... could be some kind of web based access... might fire up a Java based app for the console, etc.).
so... here's hoping I guessed correctly... your question could mean many things!!

consolefs
CONSOLEFS(4) Kernel Interfaces Manual CONSOLEFS(4)
NAME
consolefs, C - file system for console access
SYNOPSIS
aux/consolefs name dev [ name dev ... ]
C system
DESCRIPTION
To ease administration of multiple machines one might attach many serial console lines to a single computer. Consolefs is a file system
that lets multiple users simultaneously access these console lines. Each name/dev pair represents the name of a console and the serial
line device associated with it. Consolefs presents a single level directory with two files per console: name and namectl. Writes of name
are equivalent to writes of dev and reads and writes of namectl are equivalent to reads and writes of devctl. Consolefs broadcasts any-
thing it reads from dev to all readers of name. Therefore, many users can con(1) to a name, see all console output, and enter commands to
the console.
To keep users from inadvertently interfering with one another, notification is broadcast to all readers whenever a user opens or closes
name. For example, if user boris opens a console that users vlad and barney have already opened, all will read the message:
[+boris, vlad, barney]
If vlad then closes, boris and barney will read:
[-vlad, boris, barney]
Consolefs posts the client end of its 9P channel in /srv/consolefs; mount (see bind(1)) this file to see the consoles. An example of 2
consoles complete with console logging is:
% aux/consolefs bootes /dev/eia0 fornax /dev/eia1
% mount /srv/consoles /mnt/consoles
% ls -p /mnt/consoles
bootes
bootesctl
fornax
fornaxctl
% cat /mnt/consoles/fornax >> /sys/log/fornax &
% cat /mnt/consoles/bootes >> /sys/log/bootes &
The rc(1) script C automates this procedure. It uses import(4) to connect to /mnt/consoles on the machine connected to all the consoles,
then uses con(1) to connect to the console of the machine system. The script must be edited at installation by the local administration to
identify the system that holds /mnt/consoles.
FILES
/srv/consoles
Client end of pipe to server.
