Multi-boxing with clients (Mouse & Keyboard simulation)

To whom it may concern, DDSGroup is looking for a developer for one of its many projects, feel free to read about it down below. We would like to be able to simulate all mouse and keyboard events onto different clients on one computer. We will be running one main client (human) and 1 ~ 20 sub clients (simulated from the main client). If the main client turns the camera around its character, all sub clients should do so as well. The same goes for mouse clicks, if the main client clicks anywhere on the client, all sub clients will do the exact same thing. In the gaming industry they call this "Multi-boxing". There is a picture down below to hopefully give this project a more clear explanation of what we want to achieve. We are looking to have 1 developer for many other projects similar to this in the near future. Price, time and professionalism is a key Kind Regards, Ricardo
