Structured Wiring Questions.

[Matias Silva <matt@xxxxxxxxxx>]

I am looking to run the following throughout the house:

1. Coax for cable tv.
2. Coax satellite tv.
3. Cat5 for an analog phone line.
4. Cat5 for Voice-over-IP phone line.
5. Cat6 for Ethernet/Internet

I'm planning it so that all the cabling comes into a control center located on the 2nd floor.  The house is a two story house and it was built in 2000.

My questions are:

1. What is the best way to run wire from the attic through
    the 2nd floor ending up at the bottom floor.  Do I make 1 ft.
    diameter holes in the walls to drill between floors?

2. How do I navigate around/through firebreaks located on the
    exterior walls?

3. Would you recommend that I run 1" - 2" diameter pvc piping so that
    I can run the wires in the piping.  What this allows is for
    me to add or remove wiring easily at a later time.  My only concern
    is that I will weaken the structure of the house by running pvc
    through the walls and between floors.

4. In terms of the list above, should I add anymore type of wiring?
    I was thinking of an intercom.

Thanks in advance,
Matt
