There are a couple approaches to take.  One is to get it small enough 
that at least the root filesystem can be loaded in a ramdisk, then the 
CD mounted on /mnt and other filesystems get loopback mounted (/var, 
/usr, /home, etc [but not /etc ;)]), then you mount more ramdisks on top 
of this in places that need to be read-write.  It's ugly, but it works 
and wont' break anything as you have read-write filesystems.

The other option is to modify the system to tolerate readonly 
filesystems.  This isn't exactly easy to do, and you'll almost always 
have a few places mounted on ramdisks (tmpfs) anyway to run any major 
apps, but it has a smaller memory footprint and isn't as complicated.

Remember, you can burn any filesystem onto a CD-ROM.  You're not limited 
to iso9660.  This means you can have a full ext2 filesystem (for 
example) on the CD, not having to sacrifice attributes for CD 
compatiblity (though Rock-Ridge is pretty good, it doesn't have everything).
