As has already been pointed out, it is possible to burn different file system 
types to cd. In fact, a file system isn't even necessary as I discovered one 
time when I accidentally gave cdrecord a tarball as input rather than the iso 
image.  No trouble accessing the file thanks to the magic of *nix... just had 
to give tar the device rather than mounting it:  tar xzf /dev/cdrom.  he he.

At the time I tried doing it I was attempting to incrementally build a file 
system for archival purposes... something mkisofs can't do as it's not a 
'real' read/write filesystem.  I built a 650M ext2 file system in a file, 
mounted loopback.  I could daily add files to be archived and write it to cd 
when the file system was full.  Ended up being too much work though.
