Wow, 2 months later. It took me this long to decide I guess. And get off my lazy butt and call.

Well, I called DirecTV to ask the million dollar question today. They say I can add service w/out a land line, but cannot get a DVR, my purpose for switching.
So then I call Dish network and they say for a $5 monthly fee I can have anything I want without a land line! Woo Hoo!

They come to install for free on Saturday!
Just thought I'd answer the age old question for anyone else wondering.
