What you're describing here is not actually multi-threading, it's 
multi-process…ing. The keyword you're looking for is 
"inter-process communication".

You have a huge range of possible options for implementing this. 
Your decision would depend on your operating system, your 
existing implementation with sockets, and desired performance.

My suggestion: try just using sockets between processes on the 
same PC. You might not even need to add any new code to support 
this method, and it might be faster than you'd expect.
