#### Projects using godbus
- [notify](https://github.com/esiqveland/notify) provides desktop notifications over dbus into a library.
- [go-bluetooth](https://github.com/muka/go-bluetooth) provides a bluetooth client over bluez dbus API.
- [playerbm](https://github.com/altdesktop/playerbm) a bookmark utility for media players.
- [iwd](https://github.com/shibumi/iwd) go bindings for the internet wireless daemon "iwd".
Please note that the API is considered unstable for now and may change without
