Thanks.
I'm not sure how much leverage I have. They may have to run a cable to my house, just my house. I'll give it a try and report back.
Do you know anything about the hardware requirements. For example, if my wife wants a second cable output in her bedroom, does a single incoming cable go through and experior wall, then to a splitter box, then two lines come from the splitter, or is there some other physical arrangement? Do I wire the attic and house, then have an open cable exposed outside of the house with which Comcast can connect?
