I don't like doing phone and cable either but you're going to have to, especially in a new construction. They'll will say why can't you do it, it's a wire? Like was said everything is a home run. I try to run a cat5 and a rg6 together to one low voltage opening, then you can put them both in the same plate. But I don't think you can use one cat5 for both network and phone. Usually from the computer router you need a cat5 to every other computer. I tell the customer I can run the wire but you have to get a TT guy or the cable company to do finish install. It's a lot of work if you think about it, usually every bedroom, living room, family room, and sometimes the kitchen. At least it's new. I flat out refuse to touch a big rat's nest of phone wires you might see in a home, (after having a few bad experiences, naturally) A good excuse is "I don't have the right tools for those little wires". As was also mentioned it's pretty easy to pass off the alarm to an alarm company, and central vac I've never done but it was just added to a house I have coming up. I told the GC I didn't want to do it other than the plug, he said he'll do the pvc and I can run the wire. We'll see.
