This kind of notification is something that kdbus is increasingly being used for on Linux.  The primitive allows events to originate either in the kernel or in userspace and to be sent either point-to-point or to a bloom filter set of recipients (so you occasionally get some messages you're not expecting, but hopefully don't get too many spurious wakeups).
