RC4 Attack

Has somebody experience with attack on RC4? I am interested for case when we have known key length, we have encrypted message and we know start bytes from original message. I read a lot of PDF's but i don't find something "practical", no applications for analyzing this scenario... BF attack doesn't have sense (160bits, 20 bytes), maybe something more scientific.. Any ideas?

Some people think that the NSA can decrypt RC4 in real-time, but nobody knows how. Maybe they have enough computing power or they have found a nonpublic security hole. You will not find a practical public attack against RC4. If you can invent a practical attack, you will earn a bag of money.
