The project is currently paused but that was what I began to implement,
using another library for networking (RakNet). Not sure if it provide an
equivalent but if it don't I can still use boost::asio just to do this.

So if you tell me it's a safe enough way to handle it using this approach (I
don't feel confident in the communication domain so I'm never sure...yet),
as I have the source code of both processes, I guess I'll continue on this

That's a good idea, I'll see if I can use it that way.
