Given that the majority of telemetry has no external dependencies (jansson
is only used for the older compatibility part), and it uses sockets for
communication, is there a reason why it can't just be made to build and
work on windows? The unix domain socket could be converted to a standard
UDP socket on localhost, perhaps. Is there anything unix-specific beyond
that?
