This is the gist of jdownloader (a program I LOVE!!!!)

JDownloader is open source, platform independent, and written completely in Java. It simplifies downloading files from One-Click-Hosters like Rapidshare.com or Megaupload.com - not only for users with a premium account but also for users who don't pay. It offers downloading in multiple parallel streams, captcha recognition, automated file extraction, and much more. Of course, JDownloader is absolutely free of charge. Additionally, many "link encryption" sites are supported - so you just paste the "encrypted" links and JD does the rest. JDownloader can import CCF, RSDF and the new DLC files.

It is one hell of an amazing download program. And if you copy a link from a website, it will catch the link being copied to the clipboard and scan it if it can download it. And when downloading from hosters (aka Megaupload) you must agree to an agreement from Megaupload, but thats it. It even keeps track of your accounts on the hosters as well.
