You probably need to be more specific to get many useful responses.  What
do you expect N to go to?  Why do you use multiple ports?  Why are you
using UDP?  What do you mean by "robust"?  What does the Fibonnaci calculation
have to do with the application?  Is the keyboard input handling code
relevant or just part of the example?  Is win32 your development platform
or your deployment platform or both?
