you'd probably have to make your own cd that can

the switch had to be on in order to get the cd tray out

never allow root access over incoming ssh
- login as ridge than su to root
- in order for ssh to happen ..
- you presumably have network connection
when it boots off cdrom
- how do you define your ip#
( static ip# or dhcp )
- presumably written into /dev/ramxxx
- /etc/passwd and /etc/shadow should have
different passwd on each machine
- if you leave /etc/shadon on cdrom,
than each system has the same login and passwd
( all machines is hackable if one is )

you're lookng for a "standalone cdrom" or "rescue cdrom"
- gazillion of them too
other things to worry about
/var/log - what do you want to do with logging info
/var/spool .. usually needs to be writeable
- writable info will usually be in ramdisk
/var/log --> /dev/ramxxx
- which apps do you intend to run "off cdrom"
- fairly simple to do all that stuff that you're thinking about
