I think what you are talking about is udf packet writing.  This appears 
to be possible in linux, but may take some effort.  Take a look here: 
http://w1.894.telia.com/~u89404340/packet.html.  You need to patch and 
recompile the kernel, install some tools, and do some stuff in /dev. 
Since multisession writing meets most of my needs, I'm not overly 
motivated to check it out.  Has anyone on this list successfully used 
udf packet writing in linux?
