Create a TCP server. Have each client connect. In your TCP protocol with the clients, create each packet with a 2-byte prefix of the total size of the following message.

Clients then call read(max_size=2) on the socket to determine the size of the next message, and then read(max_size=s) to collect the message.

You get reliable, ordered messages, simple. You don't need a messaging framework for this one.
