There are sites that claim to be able to let you download rapidshare files without waiting, but they hardly ever work.
The secret is, the guy who owns the site buys a rapidshare account and when you paste the link into the site you're using his account, so it's not really a hack at all, and even a paid account has bandwidth limits and it's all used up not long after it's reset at midnight, which is why those sites rarely work.
