I'm not sure this would be appropriate replacement for the control
interface.. I want to be able to live without dependency on D-Bus here
and we already have a separate D-Bus interface. I was thinking more of
using SOCK_STREAM with AF_UNIX socket or SOCK_SEQPACKET for that matter.
Anyway, since these would result in having to modify all client
implementations, these are not really easy steps to take and if taken,
this could as well move to any other mechanism as long as it does not
come with unacceptable dependencies on external components.
