I was very surprised to see the article Some Students Use Net To Hire Experts to Do Their School Work on WSJ by Lee Gomes. I had written about exactly the same topic on 20th October 2005. My article was titled:
Outsourcing Homework to India. It talks about the phenomenon of outsourcing homework and specifically highlights the Rentacoder issue - "If you glance at rentacoder you will find several homework assigments up for outsourcing. In fact they have a Personal Project / Homework Help category. At present there are 88 open jobs in Homework category."
