We already know how we would have done this. You would have a limit to download each day and at a fixed speed. If registered at a cost of like 10 bucks, you could download as much as you wanted for a week and stuff..... We already know how we would do it.
But... seems like it's too risky so this project wont happen.
Only thing that would be legal to host are all Amiga demos.... but I'm not much of a demo fan..... but still... maybe could do the ultimate amiga demo download site instead?....
