what do you guys think of a "free" style licenced BSD based firewall on a 
bootable CDROM?  i know that suse linux provides this as a linux based 
product but it is commerical, and i'm not sure how popular it is or how well 
it works.

i was thinking that i could make an ISO image that when burned to a CDROM, 
which when booted it would copy itself to memory, and then run from there.  
you could setup a ram drive to be the /tmp directory, and optionally you 
could have a hard drive to hold the log files.  that way if it ever got 
cracked, all you'd have to do is reboot it to be back to a known good state.  
since the CDROM is read-only there is nothing the cracker could hurt except 
the logs, which could be setup to be emailed to you via cron.

i've talked to some people i know about this idea, and someone pointed out 
that you'd have to burn a CDR every time you wanted to permenatly chage the 
firewall rules, but what would be wrong with linking the filewall conf(rules) 
file to a file on the floppy drive?  you could edit it on a different 
computer, and then set the floppy disk to be phsically read-only.  mount the 
disk and restart the firewall deamon causing it to re-read the new file.

anyone see any serious problems with this?  anyone know if there are any 
projects like this already out there?  thanks
