I've been on the Amarok 2 ML.
The target they have at this time is to expose more media device to the
scripting API so that manual scans of mounted volumes can be made, not
using Solid, then iphones can be mounted using whatever mean is
available (iFuse, sshfs, etc...).

No it is not.
iFuse shows a network object multiplexed into USB as a disk.
iPhones do not show themselves as disks outside of the camera stuff. The
music stuff is through a network protocol.
So, once more, iFuse will not put anything in HAL.

Yes, sure, because it mounts real disks/partitions.

It is the same for iFuse. iFuse deals with USBmux (network protocol) and
AFC (network service), not with disks.

So do not expect iFuse to do either.

Sure, it detects the only part that looks like a disk, and linux
supports it very well to give you acces to the pictures on the device.

True, it detects the picture device and assumes that if that part is
there, then the rest will be too.

The pictures storing part of the iPhone.

Oh, let's say I've installed it too. :o)

OK, I accept that I may be wrong on this. I will investigate that part
further. But yes, it looks like the iFuse stuff tries to declare storage
devices and volumes into HAL.
In any case, I do not like giving all my hope only to iFuse. It looks
great, but my guess is that it is far from production ready, a lot of
stuff is being re-addressed by the development team.
