Great Idea For New Webserver Software

I would like to get together a team of great C++ programmers or some other good language for my idea. I have had this idea for 3 years and recently I saw a company doing my idea, they are selling their software for over $1000 per copy. I bet in 5 years this company will have made millions by selling a simple program. My problem/question is how do I communicate this idea and still ensure that it can be a secret? How do I organize this and not have some of the programmers leave and start their own company with the software and sell it themselves? ## Deliverables The answers to my question above. ## Platform Windows NT/2000 Server/Linux/Unix
