Report to external services

For a proper system integration it would be nice if the only method to know that something happened isn't by reading a log file and parsing a text file.

I'd envision a pipe that some other process can read in binary format with the structures defined in a provided header file. A text message is also fine if it is made in an easily parsed form in a consistent format that is kept as an ABI.

The socket already exists but it doesn't seem to send events to the clients, only allows polling. An event interface would be very useful to avoid unnecessary activity on the socket just to poll for new states.
