CD Burner Auditing

[Boyce, Kevin P. (AS)]

Does anyone know if it is possible to audit what filenames users are 
burning to optical media?

I suppose I can put a watch on the /dev/sr0 device for write events, but 
this does not give me any idea what was written to the disc.  I suppose 
I could also set an execve watch all burner programs, eg. /usr/bin/k3b 
/usr/bin/brasero /usr/bin/cdrecord /usr/bin/cdrdao /usr/bin/dvdrecord,  
to know if someone opened the burning interface; but how could I tell 
what it was they were writing?

Any suggestions are welcome.
