Here's some info.
I too am looking into a UNIX or Linux certification.
If you're going to go with a Linux certification I'd choose either the Sair Linux or the LPI. The reason for this is that both are vendor nuetral rather than being specific to one distribution. So you'll learn to administrate any distribution.
RHCE is specific to the RedHat distribution and won't help you out when you have to load software on a Debian box. Debian uses there own package manager rather than Redhats rpm system.
I'm going to do the Sair probably first. Then maybe the Sun cert. like Neo was talking about.
Sair course is about $1700.00 with New Horizons. Sun Certification is much more expensive. $5000.00 to get SCSA certified. I don't know about the prices for HP-UX or LPI yet.
Hope that helps.

UML_SWITCH(1) General Commands Manual UML_SWITCH(1)
NAME
uml_switch -- switch daemon for user-mode Linux
SYNOPSIS
uml_switch [-unix control_socket data_socket] [-hub] [-tap tun device] [-compat-v0] [-daemon]
DESCRIPTION
This manual page documents briefly the uml_switch program.
This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.
uml_switch is a daemon for managing a virtual network between user-mode Linux systems, with no connection to the host system's network.
It will listen for connections on a pair of UNIX domain sockets, and forward packets between clients which connect to them.
OPTIONS
-unix control_socket data_socket
Listen on the specified pair of sockets, instead of the defaults.
-hub Act like a hub. This means that packets received will be broadcast over all virtual links. The default is to act as a switch,
where packets are only sent to the link matching the destination MAC address of the packet.
-tap tap device
Connect the switch to a dynamically created tap device on the host
-compat-v0
Specify control protocol version 0 compatibility.
-daemon Run in the background as a daemon.
