[Tfug] OT: cabling

[Bexley Hall]

Hi,

We've finally decided to bite the bullet and get rid of the
various [duplicated!] media devices scattered around the
house in favor of a centralized server (TV, phone, movies,
audio, etc.).

Currently, we have CATV, phone and CAT5 drops everywhere
(i.e., all three in each drop).  The CATV and phone (CAT1?)
lines will just be pushed back into the wall (in case someone, 
someday, decides to revert back to more conventional wiring).
So, all of the media traffic will appear on the CAT5 cable.

Is there any reason why we would want to run a *second*
length of CAT5 to each of these locations (besides covering
our backside for cable failures)?  I.e., would there ever be
a need for two active drops in the same location?

[keep in mind, this is a home, not a place of business]

Obviously, its easier to deal with the added wiring now than
it is to plan on adding it later...

Thanks!
