I prefer the Alex Larsson approach for a couple of reasons:

	* It is not clear when CD burning would begin with the
	  burn: uri.  

	* An ioctl/command setup is suboptimal, because
	  the burning process might have to deal with exceptional
	  conditions like defects on the CD, choosing a label,
	  retrying the operation.

	  These conditions would require either an elaborate
	  callback mechanism/notification mechanism that is
	  not really needed.

	* I fail to see the advantage of putting the burning code
	  in the gnome-vfs.  Using `burn:' as a staging place seems
	  like a small code addition, but using it as the actual
	  burning process produces no benefits, and makes the GUI
	  for burning more complex.

	* It just does not feel right.
