  \brief TCP/IP communication layer (proxy side module).

  This module implements the proxy side functionality to support TCP/IP
  driven remote providers. This comprises setting up a daemon listening
  for broker service requests, as well as returning function handles for
  the individual MI calls.

  This communication layer can be addressed by the resolver using
  \p TCPComm as identifier. Remote provider destination addresses are
  assumed to be IP addresses or hostnames; no colons or port definitions
  are allowed.
