It is technically possible to add some new API to gnome-vfs to allow 
it to initiate the burn operation and communicate to it during the burn 
(enumerating cdroms, selecting cdroms and parameters, getting progress 
updates, checking availible space, parsing errors, loading new blank cds 
etc). But such an API could as well be in a standalone library. In fact, I 
know at least two people planning/writing "libcdrecord".

The question is, is gnome-vfs a good place for this API? 
I want gnome-vfs to be a lean filesystem-switch kernel. It should only do 
the things it absolutely has to, and no more. It should not be a random 
dumping ground for operations that relate to I/O, especially stuff that 
very few apps will use. If it can be done outside gnome-vfs it should 
(unless there are performance reasons or other special reasons).

If someone wants to work on libcdrecord it would give the advantages 
1, 2 and 3 that alexg cites, plus it would not be linked into every gnome 
app, it would be on a separate API freeze and release schedule from 
gnome-vfs and it would mean less burden for the gnome-vfs maintainers. 

If someone actually implements[1] such a library (and its good, well 
maintained, etc) I will consider switching nautilus-cd-burner to use it.

[1] Preston Brown at Red Hat actually has some of the work for this 
library done, so anyone interested in it should talk to him.
