According to what I read, it seems that dbus uses /path/to/file to send / receive values
So maybe we can use something like [binfile] or even [textfile] to read/write to dbus.
But I may be on the wrong way...
Anyway I'll be happy to learn what you found and how you manage to do that if you succeed (and where you're stuck if you don't)

looks like I need to learn the dbus inteface properly
