Current implementation of telemetry library is based on Unix socket, we would like to enhance the scope of library to use network sockets. We understand security challenges with network sockets, to overcome them can we can think of two steps:

ZeroMQ is a good option for Transport to hide the underlying transport
variants like In-process, Intra-process, TCP.
Also, it has various different options for security backend like
http://curvezmq.org/

if we pick ZeroMQ for transport then it will translate to

1) Remove unix file socket from telemetry
2) Use ZeroMQ for local and remote messaging
3) Needs to make telemetry or dpdk depends on ZeroMQ library(Since
telemetry is experimental, I hope, we can change this)

Thoughts from others including telemetry maintainers
