Why dont you make an dropbox account place the file in there then you can just give people the account info and then no worry about being told dont share the link. It is under gnu anyways your only paying for support but if you dont need support then why pay for it? To many people miss use gnu. If people want to sell and make money dont make a gnu software that simple. For the price they want they can buy copy rights. They can sell support but selling gnu stuff is not right because gnu state that the public owns it so your buying something you own. Would you buy your own house from your self?
