I wouldn't say it's "special", exactly--usually you've got an iso with a 
squashfs blob containing a pretty normal linux filesystem inside.  I've 
never actually tried this, but based on a little reading, the modification 
steps would be something like this:

1. Mount the iso read-only
2. Copy all the files to a temporary directory in your computer's main 
  file system
3. Mount the squashfs (on the non-current exegnu image I probed,
  it was in /mnt/temp/live )
4. Copy the files out of the squashfs and into a temporary directory, 
  since that file system is read-only
5. Mess around with the files as you would on any other system
6. Rebuild the squashfs ( http://tldp.org/HOWTO/SquashFS-HOWTO/
  has fairly extensive directions) and copy it over the old one.
7. Rebuild the iso using the software of your choice (a different livecd
  distro suggests a command-line tool called xorriso, if you have no
  preference or can't get your favourite to produce something bootable)

You'll need to have support for squashfs in your kernel, but most
of the binary distros throw in everything but the kitchen sink anyway.

Best of luck.
