It's established you can run without a phone line, at least temporarily, if not indefinitely. And verifiably permanently with a very easy hack.

Now, have you called DTV to hook up service to both your boxes yet? This now jumps right back to the thread I started. I'd like to know if this is gonna be cool. Their current (written 2001) licencing agreement states that to get the special $5 per receiver deal you have to have all units connected to a phone line. Otherwise you pay full price for each. DirecTV sales person on the phone said you can have multiple without a phone line though (that's in contradiction with the printed terms I read online, but obviously we didn't bring this up)
