Virtual/Telecommuting Jobs?

There is a recent posting for two jobs on Northrop Grumman's career website that I am interested in that are listed as virtual/telecommuting jobs. Both are entry-level positions (college) and both are listed as being located in McLean, VA. Does anyone have any information on what it means to have a virtual/telecommuting job at Northrop Grumman? I know what I think it means, which would make it my dream job, but I am wary of getting too excited since they are entry-level positions and there is a location listed. I live in OK and I don't know if there would be requirements to live in VA. Also, is there a problem if I have experience but the position is entry-level (college)? My experience is approx. 2 years and would be willing to accept the position if offered. As I said, this would be my dream job (in my current profession)! Well, thanks in advance!!
