I took a look to see what the impact would be. I am not a BlueZ expert,
so Bastien, please correct me if I am wrong somewhere.

BlueZ ships a daemon and provides two main interfaces for applications
to use it:

 1) libbluetooth shared library

 2) org.bluez DBus API

The TL;DL version is that in my findings, the only package that still
needs porting to bluez 5 is blueman. Others should either just continue
working, or need new versions packaged up.


Applications that use the libbluetooth shared library
-----------------------------------------------------

The library ABI hasn't changed and the soname in 5.x is still the same
as was in 4.x: libbluetooth.so.3, so the impact should be minimal.
Everything should be able to continue working without needing even a
simple rebuild.

Applications that use the org.bluez dbus API
--------------------------------------------

The DBus service is shipped in the 'bluez' package and I assume all the
DBus API consumers have a dep on the 'bluez' package for that:

$ repoquery -q --whatrequires bluez -s | sort | uniq
blueman-1.23-6.fc19.src.rpm
bluemodem-0.7-9.fc19.src.rpm
bluez-4.101-6.fc19.src.rpm
gammu-1.26.1-10.fc19.src.rpm
ganyremote-6.2-1.fc20.src.rpm
gnome-bluetooth-3.8.1-1.fc20.src.rpm
kanyremote-6.2-1.fc20.src.rpm
libbluedevil-1.9.2-4.fc20.src.rpm
pulseaudio-4.0-1.fc20.src.rpm

I took a quick look at all the packages above and the following don't
seem to use the dbus API and have a dep on the 'bluez' package for other
reasons (use command line utilities etc.):

bluemodem
gammu
ganyremote
kanyremote

The following use the DBus API:

blueman         [Status: needs porting to 5.x]
gnome-bluetooth [Status: ported]
libbluedevil    [Status: port available in a git branch,
                 https://git.reviewboard.kde.org/r/108912/]
pulseaudio      [Status: ported]
