you'd probably have to make your own cd that can
bring your machine onto the network so ssh could work

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
