Low voltage wiring can be an often overlooked item. Couple that with VOIP and/or wireless technology and it becomes a more difficult choice for the HO/GC. I generally advise at least 1 "wired" phone (in case of a power outage, no power for cordless phones). Run CATV "home runs" from a central point to rooms most likely to need them (bedrooms/living room) and inquire about a home office/computer room. Many homeowners choose to install a wireless network (routers, printer servers, etc), rather than wired. IMHO it's better to have it installed and not need it, than the other way around. pete
