make a File sharing program like kazaa in Delphi or VB? I dont want to make anything illegal, or infringe blah blah. The reason being, is i want to make a personal P2P program, so all my mates can share files between each other, no more than 15 people will use the program, and it wont be available for download publically anyway. Only my mates will have access to the program. So is it possible, simply put? And if so, what is involved in it?
