We thought about this in the past, but it is non-trivial. This is also
one of the reasons why (in the socket API) there are no sockets per
file descriptor or you can't read from a particular stream.

So I would like to understand first what API you want and think about how to
make that work from a protocol perspective second. Simple start/stop
semantics can be realised by transferring reliably corresponding messages.
