Good.  Well done.

Simple - what you want to do is impossible - you cannot use samba to write 
a CD.  You need to use cdrecord or cdrdao.

Not security - but if you want to do this you need to write a script or an 
extension to the iso filesystem that will write an iso as a disk - it's a 
nice idea, but it sounds too complex to attempt.  You might want to monitor 
our companies GPL menu program (runs client-server and does such things - 
we have a version of it set up here where we put files into a folder 
(toburn), and the server runs mkisofs and cdrecord to create the CD).

deadtime parameter in smb.conf. AFAIR
