RE: Structured cabling was Sean Adams' ethernet MP3 player

Structured cabling yummy ;)

I have managed the installation of several 2000 plus point installations
using
both floor closet wiring and home runs ...both have their pros and
cons...in
the home environment I think anything that works is fine especially if you
are
retrofitting the cabling. In my case I have my adsl upstairs with hubs both
upstairs and downstairs lots of PCs so I find this more convenient. I also
have a major trunk (back of built in wardrobes)providing a route between
the
floors and into the loft (the closest thing I have to node zero). I am
going
to install cabling for 1 wire but I doubt I will run it in a star config
(this
can be done but can also cause problems due to maximum 1wire lengths)
rather I will run a couple of multidrops both terminated in Node Zero.
Unfortunately when retrofitting you have to be pragmatic about cable runs.
