MiracleCast - Howto
"Current State"
...
    We require direct access to the wpa_supplicant interface. No network-manager (including ConnMan, NetworkManager, wicd) provides a Wifi-P2P API so we implemented it ourselves. We really want to drop this once network-managers start exposing such APIs.
    We use our own miracle-dhcp binary as DHCP client and server implementation. It's copied from ConnMan as no existing DHCP server provides ad-hoc capabilities. Once sd-dns gains DHCP-server support, we will immediately switch to it (which should happen during 2014) and drop our helper-binary.


Can folks from the NetworkManager team & systemd-networkd team answer regarding the current status in this matter?
