Hi Bill,

I did this same research yesterday and as it turns out, I need to revise
my position on this in libipoddevice as I need to support HAL >= 0.5.6,
and thus can't rely on this property. 

Thus I will be committing a patch to make it work in < 0.5.8. It will
use the volume.is_mounted_read_only if the property exists and if not it
will fall back to legacy checks to determine of the volume can be
written to.

Thanks for looking into this though. I could have sworn
volume.is_mounted_read_only was a lot older than 0.5.8.
